Fix bug in GDALTools Assign Projection

Assign Projection uses gdalwarp, and this works correctly when a raster has no CRS assigned, however, in the case of a raster with an incorrect CRS assignment, then gdalwarp will reproject the raster instead of simply changing the assigned CRS, propagating the error. Switching the Assign Projection tool to use gdal_translate provides the intended behaviour in all situations.
