Automatically generate entity id for scripts off of the alias just as automations currently does.

I always wondered why the entity id field is still in the script editor. It should just take the alias and make an entity id out of that. If an individual pastes a script into a new script and doesn't change the entity id that is new_script the next time they paste another new script the previous script will be overwritten because they both had an entity id of new_script.
