[PATCHv2] gitweb: ref markers link to named shortlogs

[Giuseppe Bilotta <giuseppe.bilotta@gmail.com>]

This patch turns ref markers for tags and heads into links to
appropriate views for the ref name. Appropriate changes are made in the
CSS to prevent ref markers to be annoyingly blue and underlined.

For all git ref types it's assumed that the preferred view is named like
the ref type itself. For commits, we map the view to shortlog.

Following pasky's suggestion, the action used by the ref marker
is now determined from the ref type, default action to the ref type
itsef. Currently the only non-default action is shortlog for commit
refs, but the map can be expanded as needed.
