Teacher field of classroom has no enforcement

[ChrisRogersT]

The teacher field isn't required to correspond to any actual teacher in the user db.

This can likely be implemented just like all the other referential fields.

My main doubt is how to allow the user to select only an existing teacher:

• could be an alert radio options list, but that looks a little strange.
• could be a drop down
• could be a modal but thats a lot of modal for a very small functionality set
• could be an autocomplete thing but IDK how hard that is to implement
• could just be a guess and check until the validator says you found a real teacher

I guess I'm leaning towards drop down but I don't like any of the options very much

Implemented a drop down tied to user service
