* removing a font family or style now always goes through the font manager.
* removed FreeType "cache" remains (it wasn't used, anyway, and won't be used
by us).
* renamed SharedObject to ReferenceCounting as that's what it does.
* the default fonts weren't deleted on shutdown.
* added temporary work-around for waiting until a newly created entry is complete
(just waits a moment...) - this will be fixed once Haiku supports this in a
better way.
