New Crystal Desktop Search Applet

This applet is a popup applet allowing to search through your nepomuk index.
It uses the Nepomuk::SearchHitView to display results.
You'll need nepomuk-visualization/ from playground's nepomuk-kde directory for this to work.

This applet is meant as a testing ground for concepts around desktop search, a base to play around with.

By limiting the number of results, we can make the search appear faster, even fast enough so that "performance is acceptable" on my machine. While the results look very sensible to me, they're not perfect if you have the search time out.
