packaging: stage files and dynamically generate WiX installer

Like we did for Inno, we want to make the WiX installer
"dumb" and simply consume source files from a directory
tree rather than have to define every single file in
installer files. This will greatly decrease the amount of
effort required to maintain the WiX installer since we don't
have to think that much about keeping files in sync.

This commit changes the WiX packager to populate a staging
directory as part of packaging. After it does so, it scans
that directory and dynamically generates WiX XML defining the
content within.

The IDs and GUIDs being generated are deterministic. So,
upgrades should work as expected in Windows Installer land.
(WiX has a "heat" tool that can generate XML by walking the
filesystem but it doesn't have this deterministic property,
sadly.)

As part of this change, GUIDs are now effectively reset.
So the next upgrade should be a complete wipe and replace.
This could potentially cause issues. But in my local testing,
I was able to upgrade an existing 5.1.2 install without
issue.

Compared to the previous commit, the installed files differ
in the following:

* A ReleaseNotes.txt file is now included
* A hgrc.d/editor.rc file is now generated (mercurial.rc has been
  updated to reflect this logical change to the content source)
* All files are marked as read-only. Previously, only a subset
  of files were. This should help prevent unwanted tampering.
  Although we may want to consider use cases like modifying
  template files...

This change also means that Inno and WiX are now using very
similar code for managing the install layout. This means
that on disk both packages are nearly identical. The
differences in install layout are as follows:

* Inno has a Copying.txt vs a COPYING.rtf for WiX.
  (The WiX installer wants to use RTF.)
* Inno has a Mercurial.url file that is an internet shortcut
  to www.mercurial-scm.org. (This could potentially be
  removed.)
* Inno includes msvc[mpr]90.dll files and WiX does not.
  (WiX installs the MSVC runtime via merge modules.)
* Inno includes unins000.{dat,exe} files. (WiX's state is
  managed by Windows Installer, which places things elsewhere.)

Because file lists are dynamically generated now, the test
ensuring things remain in sync has been deleted. Good riddance.

While this is a huge step towards unifying the Windows installers,
there's still some improvements that can be made. But I think
it is worth celebrating the milestone of getting both Inno
and WiX to essentially share core packaging code and workflows.
That should make it much easier to change the installers going
forward. This will aid support of Python 3.

PatchReview Introduction                                  *patchreview-intro*

The Patch Review plugin allows easy single or multipatch code or diff reviews.

It opens each affected file in the patch or in a workspace diff in a diff view
in a separate tab.

VIM provides the |:diffpatch| and related commands to do single file reviews
but can not handle patch files containing multiple patches as is common with
software development projects. This plugin provides that missing
functionality.

It also improves on |:diffpatch|'s behavior of creating the patched files in
the same directory as original file which can lead to project workspace
pollution.

It does automatic diff generation for various version control systems by
running their diff command.

=============================================================================

PatchReview Options                                     *patchreview-options*

  g:patchreview_patch = {string}
      Optional path to patch binary. PatchReview tries to locate patch on
      system path automatically. If the binary is not on system path, this
      option tell PatchReview the full path to the binary.  This option, if
      specified, overrides the default patch binary on the path.

    examples:
        (On Windows with Cygwin) >
           let g:patchreview_patch = 'c:\\cygwin\\bin\\patch.exe'
<
        (On *nix systems) >
           let g:patchreview_patch = '/usr/bin/gpatch'
<

  g:patchreview_filterdiff = {string}
      Optional path to filterdiff binary. PatchReview tries to locate
      filterdiff on system path automatically. If the binary is not on system
      path, this option tell PatchReview the full path to the binary.  This
      option, if specified, overrides the default filterdiff binary on the
      path.

     examples:
        (On Windows with Cygwin)
>
           let g:patchreview_filterdiff = 'c:\\cygwin\\bin\\filterdiff.exe'
<
        (On *nix systems)
>
           let g:patchreview_filterdiff = '/usr/bin/filterdiff'

PatchReview Usage                                          *patchreview-usage*
                                                                *:DiffReview*

  :DiffReview

    Perform a diff review in the current directory under version control.
    Currently supports Mercurial (hg), Subversion (svn), CVS, Bazaar (bzr) and
    Monotone.

                                                                *:PatchReview*

  :PatchReview patchfile_path [optional_source_directory]

    Perform a patch review in the current directory based on the supplied
    patchfile_path. If optional_source_directory is specified, patchreview is
    done on that directory. Otherwise, the current directory is assumed to be
    the source directory.

    Only supports context or unified format patches.
