Import languages from Pygments

[jayvdb]

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 Pygments 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.

a relevant WIP is coala/coala#3162

Note the hard part of this is merging language versions to avoid essentially duplicate languages. See some of the logic from .misc/pygments_coalang_import.py in that WIP .
