Move a deprecated gem into vendor/gems

If a gem gets pulled from rubygems.org, but you still have it locally (or can get hold of it somehow), you can move the gem into your vendor/gems directory.

Unpack the gem into vendor/gems

gem unpack <gem-name> --target vendor/gems

Edit the Gemfile to match
