Feature/nate/updated dev env setup

In order to avoid duplicating the Ruby version between the `.rvmrc`
and the `.ruby-version`, we'll get rid of the `.rvmrc` and use the
`.ruby-gemset` file to specify the gemset. These files are supported
by RVM as documented [here](https://gist.github.com/fnichol/1912050).

This way, packages won't be inadvertently installed into the wrong
virtual environment. I tried to have the check just run `deactivate`,
but I couldn't figure out how to get that working, so the script
just bails.

* Script now installs RVM in conventional location (~/.rvm) by
  default, though it allows for the override if desired. This will
  enable folks to install edX alongside other Ruby projects also
  using RVM.
* Script now uses virtualenvwrapper to ease the process of enabling
  the edX virtualenv and to allow for easy switching back and forth
  between virtualenv projects. It now also installs the "mitx"
  virtualenv in the conventional location of ~/.virtualenv.
* Adding a .rvmrc file so that the Ruby environment will be
  automatically activated (via `rvm use`) whenever the user hits
  the `mitx/` directory.
