Review Submission: shotgun version name and changing '\' to '/'

I'm having two little issues that prevent us from using the review submission app at the moment:

- The 'Path to Frames' and 'Path to Movie' use backslashes instead of forward slashes. Is there a way to change that in the config somehow? Currently I'm coding that into the app.py of the review submission app which I'd rather avoid

- The shotgun version name generated by the review submission tool has spaces in it. I couldn't find a place to modify the version name... is there an easy way of doing this?
