Core: Fix Template Yamls for games with colon in name (#4106)

* 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
