[Distutils] toml

Learned about toml the other day, looks like it could be useful for packaging. It is an .ini-style language that maps unambiguously to a dict, supports comments, and is used by rust's packaging system "cargo". https://github.com/toml-lang/toml Unfortunately at least 3 of the Python implementations don't seem to be up to date with the current version of the spec specifically regarding triple-""" strings.
