Lucas Murray e03748fba7 Added EffectFrame, a helper class that creates, manages and caches a
Plasma frame object. There are two ways to use this class: The first is
in "static" mode which gives the frame a set geometry and will not
change, the second is an automatic mode that creates the smallest
possible frame around the specified contents. Contents can either be
normal text and/or a QPixmap, useful for displaying the caption and icon
of the currently highlighed window.
Known bugs:
 - Does not detect Plasma theme changes, known to be in the Plasma
   library.
 - Slight graphical glitches, known to be in Qt 4.5.0 RC1.
Untested:
 - What happens when there is no Plasma theme installed.
