[super] Account Login and Creation

[rufuspollock]

3 Methods of Identification:

• Username and password #12
• OAuth (via Twitter) #5 [optional]
• Setting REMOTE_USER (useful for testing) [optional]
• Sending API Key in Authorization field (or X-HYPERNOTES-API-KEY?) [optional]

API Key probably not needed at the moment since all API stuff will happen on same site as backend.

Account creation (#4)

• Visit /account/register
• Instructed to login via twitter
• Return you in normal manner
• If no user account associated to that twitter user name create new account and send to edit page (special flag to indicate creation not edit)?

  Account Login

• Login in via twitter or via username and password
• Look up user by twitter user or via username/password and pass user to flaskext.login.login_user (should not assume twitter username and hypernotes username are the same)

  Other requirements:

• Normal login should allow for 'remember me' so that user does not have to login again if they close browser
