1.7.2 Maintenance release

#87 where theme exclude list was improperly serialized causing it to reset erratically.

Revisited #82 where I missed a few HTML issues found by @Destroy666

#88 fixed where I was wasting queries :( By adding the templates used for each script to MyBB's templatelist for caching we've saved multiple queries per page with the new set up. Apologies for this gross oversight. :(
