This patch addresses two issues:
# It allows a success message to be sent if the :options/ENV contains a "NOTIFY_ON_SUCCESS". Currently it only notifies on failures, or fixes.
# It allows a BUILD_PATH to be specified *without* a trailing /. This part of the patch might save other folks some time -- it took us quite a while to track it down.. Our rake was installed in /usr/bin, and it turns out we had specified BUILD_PATH=/usr/bin in our subversion post-commit hook when it was expecting BUILD_PATH=/usr/bin/.
This patch was a team effort with my colleague Lori Olson.
There were no test cases provided with this plugin, so unfortunately none were added with this patch.
