Reduce size of repository

[ccd0]

From #829.

ccd0:

I'm personally worried that the use of CoffeeScript is limiting potential contributors.

If I may say so: One obstacle is the size of the repository. At over 400MB it takes more than one hour to do a full clone from github.

@mahkoh
I think I could get it down to ~20 MB if I removed all the builds/ stuff. Then that could go in a separate repository. But this involves rewriting history (although I would keep the old version in the other repository), so let's make this into a new issue for visibility's sake.

Alternately, if you don't need the full history, you can check out only recent history by adding --depth 100 or even --depth 1 to your git clone command line. This is mentioned in https://github.com/ccd0/4chan-x/blob/master/CONTRIBUTING.md.

As you said earlier a new repo for builds would be a good idea.
And you can do auto commit git add . && git commit -m "New build: $BUILD_NUMBER" etc. every time there build command is run.
