Remove old docs

[rotu]

Right now, the master branch has a copy of the docs per version. This is a pain because doing a naive search in the source tree brings up duplicate results (some outdated). I suspect the reason for this is because the docs subdirectory is being served at https://docs.vectorious.org/ (which, incidentally, also lacks an index page).

If the docs are to be included in the source tree, they should be at an unchanging path so they can be meaningfully blame-d and diff-ed.

Agreed, the docs are a pain atm. I have made an effort to move all docs to sphinx, if you check out the sphinx branch you can try it out with:

cd docs
pip install -r requirements.txt
make html
# builds html files in docs/_build

I still haven't figured out how to deploy it to github pages without having a copy of it in the master branch.
