Rivo Laks 0353f3376e Make effects actual plugins, so it's possible to load them on runtime. 
There's also a kwineffects library now, containing the effects API, which makes it possible to write
  third-party effects.
API isn't complete yet and for now just two effects have been converted but I'm working on it :-)
