[PATCH] gitweb: Add shorthand URLs for summary and a special html branch

[Martin Waitz <tali@xxxxxxxxxxxxxx>]

gitweb now supports URLs like .../gitweb.cgi/<projectpath> as a shortcut
for the project summary page and .../gitweb.cgi/<projectpath>/<file.html>
to access .html pages in an "html" branch.
