Add TOML support (#1488)
Add support for [Tom's Obvious, Minimal Language](https://github.com/toml-lang/toml). Some simplifications: 1. The `.`s of dotted keys are not highlighted. This is because the `.` could be inside quotes and checking that isn't easy. 2. There is no distinction between table `[foo]` and array `[[foo]]`. `foo` will be highlighted as `table` in both cases.
