[Bf-python] Feature Suggestion: Script colors

[Bart]

A guide for making better script interfaces should be published (many 
bad designs and colors used).

A way to access to the interface colors (controls takes colors of theme 
but the rest do not) of Blender would be nice too. So scripts could 
always look like the rest of Blender:

PanelColor	PanelHeaderColor
PanelAlpha	PanelBackgroundColor
TextColor	TextHighlightColor	TextInputColor
HeaderColor	HeaderHighlightColor
BackgroundColor
OutlineColor
NeutralColor	ActionColor		SettingColor
MenuColor	MenuHighlightColor	MenuBackgroundColor
MenuTextColor	MenuItemColor	MenuItemHighlightColor

Example:

glClearColor(BackgroundColor, PanelAlpha)
glClear(GL_COLOR_BUFFER_BIT)

glColor3f(PanelBackgroundColor)
glRecti(10, 10, 100, 100)
