Use Qt's Resource System (2nd approach) (#1891)

Browse Source 
* Remove bin2res, use Qt's resource system
* Use QDir search paths and QImageReader in getIconPixmap
* Don't include "embed.cpp" in plugins
* getIconPixmap: Use QPixmapCache, use QPixmap::fromImageReader
* Require CMake 2.8.9

* Fix ReverbSC embed usage
