Review request for KDevelop and Milian Wolff.


Description
-------

TL;DR: Look at the screenshots below. :)

Make the uses widget nicer.

Main changes include:
 * Fix contexts not being clickable (they were clickable but didn't work)
 * Remove the blue arrows; all widgets are expanded by default and can
   be collapsed with a small link in the text instead. This operation is
   not common enough to justify such a huge ugly button.
   (The main problem with the button was that it looked ugly, tough)
 * Contexts without actual uses are always sorted last.
 * Add some nice icons to the list.
 * Remove all the ugly frames.
 * Make text displaying code use a fixed-width font.
 * Make the tooltip use a fixed-width font too, make it smaller (just 2
   lines of context instead of 3), and highlight the line with the use
   by making it bold-face.
 * Re-format and rename all the widget headers to be more readable
   and look nicer.

I will add a few comments to the patch to explain what I was doing.

Oh and also, I had that impression for quite a while now, but right now I'm pretty sure the find uses feature is broken in some way. Just look at the screenshots: it found way more occurences in the first screenshot than in the second (which happened after a reparse of some projects). And this has nothing to do with my changes. :)
