Merge lp:~canonical-dx-team/unity/unity.fix-691651 into lp:unity

[Mirco Müller]

Hooked up the "name-changed" signal so window-titles of maximized windows get correctly updated, when a tab-focus occurs. This also correctly disconnects a registered callback from the old-view before connecting it to the new-view.

NOTE: This branch needs libbamf (rev 377) to work.
