Second Life Terrain only in file types on first run

In gimp 2.6.6 on fedora 11 (i586), your script only works the first time I load gimp.  On second and subsequent loads, the 'Second Life Terrain' is not listed amongst the file types available.  A crude workaround is to 'touch ~/.gimp-2.6/plug-ins/file_slraw.py' before loading gimp.

I have fixed the issue, here's a patch; it may not be directly apply-able, since the pre tag isn't preserving whitespace as I would expect:

Since RAW files are already grayscale, this change doesn't actually hurt anything, and it clears up both the weird startup message ("file-slraw-load doesn't take the standard save handler parameters") and allows the script to work on successive starts of the gimp.

Thanks for the excellent tools
