I finally got the git-gui code to the point where cleaning up the
user interface was possible without sending myself to the nut house.

I tried out Linus' suggestions for coloring, and I like them.  Enough
that they are now sitting in my `pu` branch on repo.or.cz/git-gui.git.

There's also a whole slew of other improvements to the blame viewer,
like being able to dig through history by clicking on commit ids,
and tooltips when you mouse over a region of the file.

Behavior on Windows is actually quite good; its less so on Mac
OS X.  I'm fighting Tk there a little bit more than I should be.
Untested on Linux, so I'd love to hear some feedback on it.
