improve --branch processing (and differentiate from # syntax)

Previously #foo and --branch foo were handled identically.
The behavior of #foo hasn't changed, but --branch now works like this:

1) If branchmap is not supported on the remote, the operation fails.
2) If branch is '.', substitute with branch of the working dir parent.
3) If branch exists remotely, its heads are expanded.
4) Otherwise, the operation fails.

Tests have been added for the new cases.

Mercurial's internal web server, hgweb, can serve either a single
repository, or a collection of them. In the latter case, a special
configuration file can be used to specify the repository paths to use
and global web configuration options.

This file uses the same syntax as hgrc configuration files, but only
the following sections are recognized:

  - web
  - paths
  - collections

The ``web`` section can specify all the settings described in the web
section of the hgrc documentation.

The ``paths`` section provides mappings of physical repository
paths to virtual ones. For instance::

  [paths]
  projects/a = /foo/bar
  projects/b = /baz/quux
  web/root = /real/root/*
  / = /real/root2/*
  virtual/root2 = /real/root2/**

- The first two entries make two repositories in different directories
  appear under the same directory in the web interface
- The third entry maps every Mercurial repository found in '/real/root'
  into 'web/root'. This format is preferred over the [collections] one,
  since using absolute paths as configuration keys is not supported on every
  platform (especially on Windows).
- The fourth entry is a special case mapping all repositories in
  '/real/root2' in the root of the virtual directory.
- The fifth entry recursively finds all repositories under the real
  root, and maps their relative paths under the virtual root.

The ``collections`` section provides mappings of trees of physical
repositories paths to virtual ones, though the paths syntax is generally
preferred. For instance::

  [collections]
  /foo = /foo

Here, the left side will be stripped off all repositories found in the
right side. Thus ``/foo/bar`` and ``foo/quux/baz`` will be listed as
``bar`` and ``quux/baz`` respectively.
