Key all spells and deployed spells to user ID

[lalalune]

Right now, in our server we are searching for spells without keying by user, and so every user can see every spell.

We want every user to only be able to see and interact with our own spells. However, in local development, we will need to figure out how to have this make sense with our login system.

Ideally for local development we will just use the user ID 0, for example, so we don't need to worry about the login system, but we should connect with @michaelsharpe on the best strategy for this.,
