A replacement for Unity's tag system
##About
Unity's Tag system isn't the best, for a couple of reasons:
- The editor must be restarted after deleting a tag (as of 5.5)
- You can't have multiple tags
- The UI in the editor isn't easy to use.
This is a replacement to all of that. It involves making a library asset with all of your tags, then adding the tags you want to a gameobject.
