Better Signup Interaction

[tzfx]

Currently, if a user submits a request to sign-up, they are logged into the application on form completion.

This login puts them in a state where they are logged in without user roles or approval, and are immediately thrown to an 'unauthorized' page and it will stay that way util they are approved and they do a refresh of the page. Two options stick out as ways to improve this interaction:

1. Do not log the user in automatically on completion of the sign-in.
2. Log them in, but make it clear that their account is awaiting approval (if the app is configured to require approval).

I am leaning toward just not logging them in at all on Signup request. If they complete signup and there is no approval step, have them manually sign in.

Additionally, it seems like we shouldn't actually allow them to log-in if their account is not yet activated. Currently, it looks like you can login without an active account and get stuck in this same state manually. As part of this ticket, we should revise the application to more clearly indicate that the account has not yet been activated and refuse to login.
