Registration adding users; Login Verifying users.
Cleaned up login code and deleted LoginPresenter class, because it was
no longer being used.
Login and Register works with new models. App data flow in the future
will be: 1) User logs in or registers while connected to the internet.
2) Parse returns the ParseUser. 3) User will be recreated locally on the
app. 4) As the user changes data on the app, that data will be changed
locally, and Parse will also be updated with the changes. 5) When the
app is closed, the local data will be erased.
Accounts loading/saving/updating working. Messy though.
Adding transactions to cloud!
Implemented getting transactions from server.
