* make custom prefixes work again

Browse Source 
* make non-frame based indicators work (sliders now show focus again)
* shave ~8ms off of creation time (bringing it down to ~1ms)
* allow sharing of the FrameSvg object
* constify and sanitize the previously existing constructor
* use QStringBuilder
