add parameter for transformation of input data to v.in.ogr/r.in.gdal

[jachym]

currently, you can not import vector or raster data, if their projection is different from your location's projection.

Adding parameter (e.g. -T for 'transform') would allow users to import data to target location and reproject them on the fly

adding another parameter (e.g. srs= ) could overwrite source file projection (or set, in case of unknown)

this would enable us to import data, without former reprojection (but you can not reproject postgis table easily) or without need for creating temporary location just because you want to import data to grass
