Upgrade strategy should allow a specific version

[cgriego]

The upgrade_rvm helper only allows "latest" and "head as valid values, but the rvm get supports a wide variety of options.

Usage:

  rvm get {stable|latest|latest-x.y|x.y.z|head|master|branch|help} [--auto]

Options:

  stable      - install the latest RVM stable release

  latest      - install the latest RVM release

  latest-x.y  - install the latest RVM release matching the x.y* pattern

  x.y.z       - install a specific RVM release

  head        - install the latest RVM development version
  master

  --auto      - automatically update shell profile files.

  help        - Output this message.

Branches:

  branch <branch>
  branch /<branch>
  branch <repo>/
  branch <repo>/<branch>

  Defaults:

    branch: master
    repo:   wayneeseguin

  Examples:

    rvm get branch shoes   # will fetch branch shoes  from wayneeseguin/rvm repo
    rvm get branch mpapis/ # will fetch branch master from mpapis/rvm       repo

When using a specific version, it would be nice if the current version were detected and rvm were not reinstalled unnecessarily.

This should be less restrictive about install and upgrade options.
