Manage installation of rake and bundler separately from core ruby packages
The ruby::bundle resource is basically a wrapper for an exec, but it knows what it requires!
Separating the bundle command into command and option parameter so some validation and sanity checking can be done.
Similarly a rake resource, with an option to feed it to bundler.
user parameter passthrough missing

rake task regex not working :(
Working on concatenating arrays...
remove undef if it's in the array
More rigiourous elimination of undef in path and environment

Tests for ruby::bundle resource
