[PATCH] gitweb: use action dispatcher for non-project actions, too.

[Martin Waitz <tali@admingilde.org>]

Allow to use the global action dispatcher for all actions by introducing
"/actions".  If no project directory is given then a / is prepended to the
action and the normal dispatcher is called.
Project list and OPML generation are now hooked into the list as "/summary"
and "/opml".

As "/" is not an allowed character in actions accepted through the CGI
parameters, it is still ensured that no normal action can be called without
giving a valid project directory.
