Add a toml esq configuration reader and writer

[GregHib]

After consideration about yaml in #618 I wrote a toml parser but it wasn't as performant as I would've liked. I came up with a few improvements over the current yaml parser I had. Namely: parsing numbers by hand and managing & reading everything as bytes rather than char arrays.
My first implementation highlighted the complexity and weird edge case design decisions for toml, like supporting a flexible version of RFC 3339 dates rather than ISO 8601, allowing multi-line arrays but not multi-line maps, and not having a way to reduce duplication of table headers.

I addressed this by implementing my own syntax, removing the complexities for my use-case and adding a select few improvements. It's closer in style to .ini than .toml but is both more limited and more expressive than either.
