[Qt-interest] Plugin framework

[Tim Peeters]

ok thanks people! I got it to work :)

I forgot to MOC my header files...

I also added the following definitions to my cmake files:

add_definitions(${QT_DEFINITIONS})
add_definitions(-DQT_PLUGIN)
add_definitions(-DQT_SHARED)


Greets,
Tim

PS: I'm really happy that it works now :D
