gitweb: Improve behavior for actionless path_info gitweb URLs

Eli Barzilay noticed that

  http://server/gitweb/project/<commit-sha1>

link goes to 'shortlog' view, while 'commit' view would be more
useful, but that 'shortlog' action is more apropriate for

  http://server/gitweb/project/<commit-sha1>..<other-commit-sha1>

links.

Therefore for the case when we don't have either action, or filename,
or parent hash [base] in path_info-based URL, i.e. for

  http://server/gitweb/project/<object-id>

link, instead of using 'shortlog' view we allow dispatch() subroutine
to detect type of object and use appropriate action (in most case it
would be either 'commit' action, or 'tag', or 'tree' for top
directory).
