[Qgis-developer] Deactivate raster icon generation by default

[Matthias Kuhn]

On linux it's in ~/.config/QGIS/QGIS2.conf (I believe in every 
distribution).
Default is still true. It's a really simple fix, I'll just commit it. 
If there's a problem, please complain.

If there's the demand for it, a threshold size (resolution * bands?) 
could be introduced (for 2.1 I'd say).
