Add support for DiffMerge

[GoogleCodeExporter]

This is an additional *free* diff program available for the Mac (and other 
platforms).

http://www.sourcegear.com/diffmerge/

This has been used extensively against DiffMerge version 3.2 and minimally with 
the new version 
3.3.  The assumption is made that diffmerge.sh has been installed into 
/usr/local/bin/.  
Alternatively, the contents of diffmerge.sh could be copied into svnX's 
svndiff.sh and assume that 
DiffMerge.app is installed in /Applications.

Additionally, since the nib file contains a binary plist, I've attached a zip 
of the modifications, but 
they were made on Leopard.  If anyone has problems with this, the only *actual* 
change made is an 
entry of "DiffMerge" in the preferences popup menu, and its tag value is 5.
