Added the miniature wormhole generator (#2800)

* Added the miniature wormhole generator

* Updated structure & tooltip and added hatch hask

* Fixed controller promotion not working

* Initial work wormhole render + spotless + git strangeness

* Fix wildcard imports

* Removed redundant code + added more reasonable defaults

* fix

* sa

* Remove debug print statements
