[PATCH 3/3] gitweb: Optional grouping of projects by category

From: Sebastien Cevey <seb@cine7.net>

This adds the $projects_list_group_categories option which, if enabled, will result in grouping projects by category on the project list page. The category is specified for each project by the $GIT_DIR/category file or the 'gitweb.category' variable in its configuration file. By default, projects are put in the $project_list_default_category category.

Note:
- Categories are always sorted alphabetically, with projects in
  each category sorted according to the globally selected $order.
- When displaying a subset of all the projects (page limiting), the
  category headers are only displayed for projects present on the page.

The feature is inspired from Sham Chukoury's patch for the XMMS2 gitweb, but has been rewritten for the current gitweb code. The CSS for categories is inspired from Gustavo Sverzut Barbieri's patch to group projects by path.

Thanks to Florian Ragwitz for Perl tips.
[jn: Updated to post restructuring projects list generation, fixed bugs,
 added very basic test in t9500 that there are no warnings from Perl.]
