Just a quick fixrelease send to the buildserver.

I noticed I had the maxvalue of the keyconfig codes set to 300, while the three most left keys have higher values. Maxvalue is now set to 307.
Next to that, I have have put a version number in the about. In fixrelease version 0.0.3-2 I did not change all the maxvalues, in 0.0.3-3 I did.
