* integration of vector icons with the registrar and the mime data base

* additional versions of SetIcon[ForType] and GetIcon[ForType] in BMimeType
  and BAppFileInfo, which handle flat vector icon data
* changes in Tracker to support scalable icons (currently broken for
non-vector icons and needs cleanup) and drawing icons correctly with alpha
channel (large parts of this work done by Michael Lotz)

If someone feels like looking over the changes, that would be much
appreciated! :-)
