Lua Qt gui building for RTTLua

For those interested:

I found out how you can very easily create QT gui's for your rttlua
applications, I'm using lqt (https://github.com/mkottman/lqt) for
this.

This gist https://gist.github.com/2249915 shows you how it can be
done, and proves that the Qt-eventloop does not block your component
threads.
