Add term colors

[johrstrom]

Replace #395 and it's branch because it got all jacked up during merges/rebases with master.

Just a note. It doesn't seem like the termite and hyper color scheme files are working. The parser expects a few properties and the files I have found so far have not provided those properties. Hyper color schemes involve nodejs and does not work with the color scheme implementation ex https://github.com/leo/hyper-native

I tried this and it immediatly crashed with this error. I take it it doesn't like the fact I don't have any schemeFiles (err directory)?

So the original goal was to have these two as separate PRs/branches, now they are coupled together as one big PR/branch... that makes it hard to review and test separately. Thoughts?
