[PATCHv5 00/12] gitweb: remote_heads feature

New version of the remote heads feature for gitweb (v5 because the previous rehash was actually v4, although I forgot to prefix the patchset accordingly).

I've included all the comments received from the previous review (unless I forgot about something), as well as the suggestions about how to select and present remotes in summary view.

The first 4 patches are rather straightforward and can probably go straight in. The 5th patch is a bugfix for something that is only triggered by the name manipulation done with the remote heads, but can probably useful even without the rest of the series.

Patch 7 provides 'single remote view', depending on patch 6 for improved visuals of the page header.

Patches 8-9 present a new routine for grouping data (will only be used by the final patch in this set presently, but it has other prospective uses too), patch 10 introduces refactors some code that is used in summary view (patch 11) and in the final version of the remotes view (patch 12).

Remotes view now displays the remote URL(s) together with the heads (or only the URL(s) in summary view if there are too many remotes), although I'm open to suggestions about the opportunity of displaying ssh URLs.

As usual, you can see it live @ http://git.oblomov.eu (look at the rbot project in particular for the "lots of remotes" case), comments welcome.
