VcRefactoring: Merged [3324:3538/trunk] (painless!)

Some minor cleanup in the font formatting code, suggested by Bjorn Swift. Thanks!

In the !OutlineFormatter, the anchor of headings must always be computed on the full wikified heading, as this is what will be used by the normal Formatter when rendering heading ids. Fixes a problem observed with long headings in the TracFaq.

Add support for labelled WikiPageName links, e.g. `[WikiPageNames wiki page name]`. This change restores the functionality of #3240 and fixes #3343.

Revert [3376/trunk/trac/wiki/formatter.py] and reintroduce explicit support for MoinMoin's internal free links which was removed in r3382. This change temporarily breaks #3240.
