Title: Document installation guide for rbenv.

This probably doesn't need to be merged as is. Perhaps the installation guide can be merged to the Readme. Just for review and feedback.

----

- Add rbenv.md with steps for getting OST up and running with rbenv.
- Remove `capybara-webkit` from Gemfile.lock temporarily.
- Add `vendor/cache` and `.ruby-version` to .gitignore.
