LuaPlayer CORE - C --> C++

[LuMo]

Would be easier to add some features if luaplayer would be taken to c++
i already worked out some stuff

• imagefilters like blur, image correction, greyscale
  channel modifications
  and to come: blend modes (which really gettin me mad on 1555 images!)

more details are on my webpage (as usual)

i am working on another library to, but do not want to talk about that before its sure that it will work (at least a bit stable ;) )

greets
lumo

PS: changed the code to .cpp tweaked some things, but getting "undefined..." errors even with using extern "C"
