[QtonPi] Bakeqtpi for osx updated

[Trismer Technologies]

Hi,

I added small improvements to the bakeqtpi script for osx which make the process much easier. Now the script on osx doesn't require sudo. Everything is built at ~/opt/ so it's much easier to add generated qmake to the QtCreator. Feel free to try it:

If you find it useful, please merge it with
https://gitorious.org/bakeqtpi/bakeqtpi master

Thanks,
