Display main repo language

[Mordax]

So this I think is a sub issue of #37 to get some practice grabbing info from the api. I think displaying the main language is still useful at a glance, but definitely will expand to see how to pull information from the languages url - just because it's none doesn't mean there isn't a ton of different languages in the repo.

Apparently Github API spits out language info via bytes of that language that was coded so gonna have to engineer something useful, like number of files out of that.
