gdal_merge.py : add support for output of nodata value

Description

The gdal_merge.py does not set the nodata value in the bands of the output file.

I have added a -a_nodata option (as in the other tools gdalwarp and gdal_translate), which adds the specified nodata value to the output file (regardless of the -a value).

+ if a_nodata is not None: + t_band.SetNoDataValue(a_nodata)

Tested on GTIFF files only. I'd be glad to test other files types if necessary.
