TortiseSVN integration: Hide temp files from Eclipse

[DanNeely]

I'm using DiffMerge as the default diff tool with TortiseSVN. When comparing a file against the checked in version a temp file (ex __5B1A.tmp) is created in the same location as the file I'm looking at. Eclipse refreshes the navigator pane automatically adding the files to its list. This is just a cosmetic nuisance for most files, but a non-Android Layout file in the layout folder results in a compile failure meaning I can't keep the diff window open if I want to make a new build (eg to make sure any pre-commit cleanup didn't break something).

DiffMerge creates the __file__ tempfiles in the same directory as
one of the files in the set. And this is hard-coded. (I just looked
at the source and confirmed that there isn't an environment variable
option to override that. Sorry.)

However, the temp files are only created as backing for editing, so
if you launch DiffMerge with -ro2, the right side will be read-only
and no temp file will be created.

I don't know if that will work for you in all cases, but it's worth a try.

I've never never used the edit feature when doing a diff, so that works. Thanks.
