Subject: 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.
