TOML-Highlighting

Fixed bare and quoted keys:

key = "value"
bare_key = "value"
bare-key = "value"
"127.0.0.1" = "value"
"character encoding" = "value"
"ʎǝʞ" = "value"

Improved TOML-Highlighting

I improved lmno's TOML-highlighting (https://github.com/lmno/TOML), but since lmno did not answer to a pull request from half a year ago, I decided to release it myself.
