Instantiate Signup.Register in Registration component

This has to be done rather than in MatrixChat because the render() calls
will create new instances otherwise. Pass in all the strings the logic class
requires to the Registration wire component. This isn't the "best" solution
because unloading/reloading the Registration component will lose registration
state which should be persisted. Ideally we'd DI from the top to ensure this
can't happen (as opposed to relying on module globals...)
