Update Gemfile dependencies.
Add Ubuntu 13.04 and Debian 7.1.0 as Test Kitchen platform targets.
Refactor RVM installation code into rvm_installation resource.

This is a nontrivial update and not 100% backwards compatible.
Update default ruby attribute

This is now set to 'ruby' which will always be the latest version and
patch release of ruby according to the current version of RVM being
installed. Overall, this is a more sensible future-proof default than
constantly updating patch levels in the default attributes.
Update vagrant and berkshelf links
Refactor install/force actions in rvm_installation.

Thx to @mpapis :)
Add new .footdcritic tags setting file
Upgrade gems
Remove deprecated FoodCritic rake task

Lock foodcritic to latest release
Include the FoodCritic rake task
Add resource notifications to LWRPs

Resolves [FC017](http://acrmp.github.io/foodcritic/#FC017)
Add apt to the runlist on this suite

It will fail due to a missing apt mirror and it needs updating before
attempting to install a few packages.
Updating to the latest patch release of 1.9.3

1.8.7 is officially EOL so it will slowly be removed from the
integration suite.
Update bats tests

This will help better test the system and user based installs of rvm
because it will need sudo access in order to execute any of the rvm
commands as that user for the user installation.
