GUI: Fix tooltip drawing

With help of Tanoku tooltips were switched from widgets to dialogs
which helped to fix nasty bug with background not being restored.
Although it is basically a hack around inconsistent font backbuffering
in our GUI code, for the time being it is feasible.

The patch was extended with way to specify tooltip background in the
theme file.
