Made colors configurable

Added a tab to ConfigurationDialog to make some colors configurable. It
works somehow. The font color isn't evaluated yet, since I'm not
convinced that it is a good idea.

But one problem is that calling qApp->setPalette() doesn't propagate to
non visible child dialogs. Dunno if it's worth fixing.
