[PATCH 2/3 (take 2)] gitweb: Allow for href() to be used for links without project param

[Jakub Narebski <jnareb@gmail.com>]

Make it possible use href() subroutine to generate link with
query string which does not include project ('p') parameter.
href() used to add project=$project to its parameters, if it
was not set (to be more exact if $params{'project'} was false).
Now you can pass "project => undef" if you don't want for href()
to add project parameter to query string in the generated link.

Links to "project_list", "project_index" and "opml" (all related
to list of all projects/all git repositories) doesn't need project
parameter. Moreover "project_list" is default view (action) if
project ('p') parameter is not set, just like "summary" is default
view (action) if project is set; project list served as a kind
of "home" page for gitweb instalation, and links to "project_list"
view were done without specyfying it as an action.

Convert remaining links (except $home_link and anchor links)
to use href(); this required adding 'order => "o"' to @mapping
in href(). This finishes consolidation of URL generation.
