Ch 1147: Allow deletion of goals

Includes the deletion of goals but also a maintenance task to split the acquia_lift.personalize.js file into several smaller js files for manageability.  You can see the actual changes made to the individual files in the commit history rather than the full file change history.
Well we can delete a goal that is from a visitor action defined in code so it is still valid.  We just load this here to get the label for the action.
