The gist of the commit are a few improvements in the
create action, where:
* long boolean statemenst have been wrapped in smaller more readable
methods.
* the 3rd party user info creation has been extracted (still in controller)
* a small helper method for creating a new user from params (to reduce
visual clutter)
* specs have been added where I came across untested methods/branches
Other changes are more trivial like formatting and whitespace fixes.
Hope this helps. Regards.
* rename `User#password_required` to `User#password_required!`
* emails with "i" @ something are a special case as well
* get rid of `self.` and returns where possible
* prefer "unless a" instead of "if !a"
* `unread_notifications` without manually iterating
* introduce `User#moderator?`
* introduce `TrustLevel#valid_key?`, `TrustLevel#compare`, and
`TrustLevel#level_key`
