clean up account system #32
Description
The account system was modified example code and includes a lot of cruft. The example code was a bit messy as well and included some code that seemed unnecessarily complex. Some was removed, but other parts still remain.
For example, the account system doesn't use authentication tokens [well] and may currently break if the system requests that a user confirms their credentials (I have no idea what triggers that). Ideally, the system should never keep the user's password on the device, only use something like OAuth to store a pairing.
