* add quotes around strings containing {{ game }}
* do the actually correct thing instead of a hack
thanks berserker66 for pointing out to me that I was doing this the
completly wrong way, so I fixed it up
* Clean up filenames to prevent illegal chars
* Use %s substitution instead of concatenation
* whoops
somehow i removed a space from the comment for the regex, so this adds
it back
* Use pre-existing function in Utils.py
* Test: add test for option yaml with colon
