Consider referencing this package in Linguist

[tschf]

Linguist is the repo that maintains what language code files hosted on GitHub are. Currently it references the text mate bundle this repo was based off, as the syntaxes expand in this repo it might be better to reference this instead.

They are referenced as a submodule. Mostly, they are text mate bundles, but there are a couple that are just over a dozen that are referencing atom language grammars, e.g language-python

See: https://github.com/github/linguist/tree/master/vendor/grammars

So far the main change is adding APEX related words.
