Awesome Andreas!

I haven't looked at the patch yet, but it is good that you are taking this on.   
KDevelop works 'good enough' with Qt4 for me by just setting the ( three 
different sets ) environment variables in configure/make/run, however I'm 
sure more Qt4 integration will be appreciated.

Regardless, it is good to see some patches for this.  Welcome!
