[PATCHv3 3/4] gitweb: separate heads and remotes lists

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

We specialize the 'heads' action to only display local branches, and
introduce a 'remotes' action to display the remote branches (only
available when the remotes_head feature is enabled).

Mirroring this, we also split the heads list in summary view into
local and remote lists, each linking to the appropriate action.
