Import languages from Linguist #95
Description
Create a script, any language, which must be checked into /tools/ in this repo and be run in Travis CI, which creates data files for any languages that are in Linguist https://github.com/github/linguist/blob/master/lib/linguist/languages.yml but are missing from coAST.
This would replace coala/coala#4556 .
Try to include as much information from Linguist as possible, enhancing the local schema as needed.
