Add multi-channel "import" to r.external (as in r.in.gdal)

[neteler]

Currently, r.external "imports" only the first channel, not all available channels as r.in.gdal does:

r.in.gdal 014_03.jpg out=mymap -o
WARNING: Over-riding projection check

r.in.gdal complete. Raster map <dd.green> created.

The behaviour of r.in.gdal is more user-friendly, could r.external be improved?

thanks, Markus

As always, it works out of the box :) Also tested with appropriate modifications in 6.4.
