Add commas between PercentageTerms in keyframes (#151)

Fixes #105

A previous attempt unconditionally added commas between `PercentageTerm`
values, but those terms can also show up in places where commas are not
expected.

Add state on the visitor to track whether we are in the context of a
`keyframes` rule. I _think_ these are the only rules which need comma
separated terms, and that it can't be nested in a way where naively
reverting back to `false` after leaving should cause any problems.
