Title: added rbenv-check. checks rbenv installed and configured correctly

Specifically it checks that:

1. rbenv bin directory is in path
2. rbenv in bin directory is executable
3. rbenv shim directory is in path
4. `which ruby` returns the shim ruby and not system ruby

It outputs in convenient color coded format that draws attention to problems.
