Now that we have gems:unpack and gems:build allowing for integration of

100% of your gems into vendor/ it would be nice to have the ability to
automatically unpack the full dependency tree of your specified gems.

This patch adds the rake task gems:unpack:dependencies to do this.

Usage:

gems:unpack:dependencies          # unpack all dependencies
gems:unpack:dependencies GEM=foo  # unpack all dependencies for gem foo
