Rework drawing of FunctionBar

Browse Source 
Draw the FunctionBar within Panel_draw instead of manually throughout
the code.
Add an optional PanelClass function drawFunctionBar, to allow specific
panels to override the default FunctionBar_draw call.
Rework the code on color change, to really change all colors (selection
markers and panel headers).

Closes: #402
