Subject: Add Gemfile entry when creating a plugin in application's directory

After vendor/plugins were removed from rails, the new method to create
plugins is to create gem plugins. Most of the time if you create a
new plugin in rails application's directory, you want to extract
something from that application and use it immediately, ie. add
such line to Gemfile:

  gem 'foo', :path => './vendor/foo'

This commit makes plugin new generator to add such line automatically.
