Previously, rbt patch would not work with SVN repositories. This was

because the the value for patch's -p flag was being calculated

incorrectly for SVN repositories. This has been corrected and now we use

svn patch to apply the patch instead of the patch executable. This

allows patches containing SVN keywords to be applied.

Ran unit tests.
