This is the first step towards a better looking and more usable metadata GUI.

- A nicer comment widget shows a popup to edit the comment.
- A tag cloud replaces the ugly tagwidget from libnepomuk.
The plan is to use Dolphin as a testbed to optimize the look and then 
move at least the tagcloud to libnepomuk to make it available for all apps
since this is a common feature.

So please test it and provide feedback. The layout is still cluttered. So we
also need feedback on that. And of course on the usability.

Apart from the GUI Dolphin now uses the mass metadata update job to perform
metadata updates on many files in an async KJob without blocking the GUI.
This is another candidate for public API at some point.
