Add simple palette to tst_QWidget

Browse Source 
When a widget's palette has different active / inactive colors,
multiple paint events can occur. This makes tst_QWidget functions fail
when they expect a spcific amount of paint events and the platform
theme provides a palette with active / inactive differences.

This patch adds a function to populate test widgets with a simple
palette, to prevent multiple paint events.
