Use flask to render site and get rid of submodules

We don't want to use statically generated html files anymore. We are using
flask to do the routing and render the templates for now. This means we also
get rid of the submoduels and put everything together in templates/.

+<h1>Quick Start</h1>
+<p><em>How to get going at once.</em></p>
+<h2>Part 0: Instant usage</h2>
+<p><em>(you know this from the main page)</em></p>
+<p>Clone a project and create a patch </p>
+<pre><code>$ hg clone http://selenic.com/repo/hello
+$ cd hello
+$ (edit files)
+$ hg add (new files)
+$ hg commit -m 'My changes'
+$ hg export tip &gt; patch.diff
+
+</code></pre>
+<p>Create a project and commit </p>
+<pre><code>$ hg init (project-directory)
+$ cd (project-directory)
+$ (add some files)
+$ hg add
+$ hg commit -m 'Initial commit'
+</code></pre>
+<h2>Part 1: Using Mercurial</h2>
+<p>Aside from the practical Quick Start above, there are only a few commands you need to start
+working. </p>
+<p>Even if you stick to these basics, Mercurial is quite powerful. And they are very easy to
+use, once you see the model behind them: Each repository has the whole history, and history is
+not necessarily linear (part 2 explains that model in a bit more detail). All that history is
+stored in the ".hg" file inside the top-level folder of your project.</p>
+<p>A quick overview of the basic commands: </p>
+<ul>
+<li>hg init: create a new repository
+</li><li>hg commit: save your changes in the current repository
+</li><li>hg log: see all changes in your repository
+</li><li>hg pull: get all changes from another repository into the current one
+</li><li>hg push: get all changes from your repository into another one
+</li><li>hg serve: create an instant-webserver. People can see the history there and pull from it
+</li><li>hg merge: join different lines of history
+</li>
+</ul>
+<p>If you want to see a nice graph of the history, just do <hg>hg serve</hg> in your repository and then direct your browser to </p>
+<pre><code>    http://127.0.0.1:8000
+
+</code></pre>
+<p>This also helps getting a feeling for what the commands do. </p>
+<p>(you can also do a lot of finegrained stuff by using different command options. Just call "hg help &lt;command&gt;" to see them). </p>
+<p>One step you'll likely want to do is setting your username in your Mercurial config file. </p>
+<p>For this you can configure a proper name and email address in ~/.hgrc (or on a Windows system in %USERPROFILE%Mercurial.ini) by adding lines such as the following: </p>
+<pre><code>[ui]
+username = John Doe &lt;[e-mail]&gt;
+
+</code></pre>
+<p>I you want more than this quick overview, please have a look at our longer <a href="/guide">practical guide</a>. </p>
+<h2>Part 2: Understanding Mercurial in 6 steps</h2>
+<p>Now we'll look at some of the basic concepts of Mercurial to get a better understanding of its internals: </p>
+<ol class="undecorated_list">
+<li>
+<p>Like in Subversion, history consists of a number of commits. They're
+  called changesets in Mercurial.</p>
+
+</li><li>
+<p>Subversion requires a strict linear ordering of the commits and
+  gives nice linear revision numbers to them. So revision N has only
+  one child revision, N+1. This is simple, but it requires a central server to make sure that
+  everybody agrees on the revision numbers.</p>
+
+</li><li>
+<p>Mercurial generalizes this by letting each changeset have multiple
+  children. If I work alone and make commits I'll make
+  <img src="/images/quickstart-c1.png" border="0"/><br />
+  by making three commits. </p>
+
+  <p>The commit C3 with no children is a "head".
+  It is also the newest changeset in the repository -- called "tip". If I shared C1 with you and you started your work from that, your
+  commits will build a repository like this:
+  <img src="/images/quickstart-c2.png" border="0"/><br />
+  Here C3' is a head in your repository and I don't know anything
+  about C2' and C3' yet.</p>
+
+</li><li>If I pull from you, or you push to me, the two repositories are
+  compared. By default, all missing changesets are transferred. This
+  is all there is to push/pull: compare two graphs of changesets and
+  transfer the missing ones.
+<p>After a pull from you my repository will look like this:
+  <img src="/images/quickstart-pull.png" border="0"/><br />
+  Here C1 has two child changesets, and the repository has two heads
+  since the development has diverged.</p>
+<p>The changeset C3' will be the new tip since it is the newest
+  changeset in the repository. Note that tip is always a head, but a
+  head need not be the tip.</p>
+
+</li><li>Having two heads suggest that someone should merge them -- otherwise
+  the changes from one will never be combined with the changed made in
+  the other head.
+<p>When merging with 'hg merge' the task is to figure out the canonical
+  way to combine the changesets. If the changes do not overlap this is
+  usually trivial, otherwise you have to do a three-way merge. The
+  merge must be committed and this creates a changeset which explains
+  to the world how you think the two heads should be combined:
+  <img src="/images/quickstart-merge.png" border="0"/><br />
+  Note that the merge changeset M has two parents.</p>
+<p>If you do not merge C3 and C3' and try to push, you get the 'new
+  remote head' message and push aborts. It aborts since it is a little
+  "impolite" to leave the job of merging to someone else -- he who
+  created the two heads by pulling in some code should also normally
+  do the merging.
+</p>
+</li><li>
+<p>It helped my understanding a lot to think in terms of the changeset graph. Just remember that:</p>
+<ul><li>
+<p>"hg commit" adds a new node. The parent changesets of the new node
+    is given by "hg parents"</p>
+
+</li><li>
+<p>"hg push" and "hg pull" transfer nodes in the graph between two
+    repositories.</p>
+
+</li><li>
+<p>"hg update" updates the working copy to reflect a given node in
+    the history graph. This also changes the parent changeset of the
+    next commit, see "hg parents".</p>
+</li>
+</ul>
+</ol>
