hgweb: provide links to branches, tags and bookmarks by name (paper and coal)

hgweb: provide links to branches, tags and bookmarks by name (paper and coal)

It's sometimes handy to, say, have a url always point to branch head, not just
at the current branch head by node hash. Previously, this was only possible by
manually editing url and replacing node hash with branch/tag/bookmark name. It
wasn't very convenient, or easy - in case the name contained special
characters that needed to be urlencoded.

Let's have /branches, /tags and /bookmarks pages in paper and coal style
provide links both to symbolic revisions and to node hashes.

This feature was wished for in issue3594.
