This is just some minor whitelisting/additions to dictionaries to catch up between when the spell checker PR was written and when it was finally merged.

This is basically taking the output from 499f24a#commitcomment-38053489 and putting it into files.

The choice of files is arbitrary. I'm adding a math.txt dictionary because it's a reasonable example.

The goal here is to get master to a green check mark
