Image plugins potentially not included in binary versions

[GoogleCodeExporter]

I haven't verified whether this affects any RGG versions as of yet, but while 
building another program with pyinstaller, I noticed that the PyQt4 image 
format plugins (among others) were not being correctly included in the output, 
resulting in the program not being able to open jpeg and other plugin-based 
formats. We should remain alert for this as a potential source of issues with 
the Windows releases.

Not really relevant these days.
