[Qgis-developer] Deactivate raster icon generation by default

[Ziegler Stefan]

Yes, I was wondering few days ago why I took half a minute to load a VRT... Then I realized that turning off "create raster icon" speeds the loading a lot. There is no noticable lag of time now when loading 2 large VRTs (approx. 80 GB aerials each VRT).

Regards
