Support for Sandia National Laboratories GFF data format

Description

This patch provides rudimentary support for the Sandia National Laboratories GSat File Format image data. This data is generally complex, however, there is support for images with 1 byte/pixel (and this case is accounted for, though untested due to a lack of data).

This format is read-only, and very limited metadata support exists at present. The next goal is to include more detailed polarimetric information, as well as date/time information and instrument parameters. Unfortunately, no data on the format has been made available to me other than a Matlab program to parse the data, so support for much beyond that is a bit hectic.

Sample data for this can be found at http://sandia.gov/RADAR/sar-data.html. The format was tested using gdal_translate (to translate it to a GeoTIFF image) as well as OpenEV to display both the resulting GeoTIFF and the image itself.

Patch applied and some manual reformatting done.
