collision between files on case insentive OSs

[gwalth]

On git clone, a collision between the two files modules/idl_downloads/drpXlateFileName.pro and
modules/idl_downloads/drpxlatefilename.pro

This will fail on case insensitive OSs (why are there case insensitive OSs?), just rename the file to ...old or if it is deprecated, remove it.

Cheers,

Greg
