merge --squash openid branch to take care of a false merge commit in the

basic_auth branch that openid is forked from

Commits squashed together (in reverse chronological order):
 - do the label thing only for boolean fields
 - made edit_account to autofocus on the first field
 - added feature to render_divs where if field.label == '' then it
   will render form.description the same a render_label
 - added allow_registration check
 - refactored create_user
 - removed verification_key from create_user
 - removed get_user from openid
 - cleanup after removing openid from template_env.globals
 - fix for werkzueg 0.9.1
 - cleanup after merge
 - more tests
 - restored openid extra_validation just for safety
 - tests for openid
 - deleted openid extra_validation
 - passed next parameter in session for openid
 - fixed a bug that was deleting the messages
 - implemented openid store using sqlalchemy
 - ask openid provider for 'nickname' to prefill username in registration form
 - refactored delete openid url to work with generic urls such as
   google and to not allow a user to delete a url if it is there only
   one and they don't have a pw
 - refactored login to register user workflow, which fixed a problem
   where the 'or register with a password link' wasn't showing up when
   the finish_login view called the register view because there wasn't
   any redirect.
 - added the ability to remove openid's
 - added the ability to add openids to an existing account
 - refactored start_login and finish_login views
 - modified edit_account.html to use render_divs
 - modified gmg/edit/views to behave appropriatly if no password
   authentication is enabled. moved the update email stuff to it's own
   funtion to make edit_account view cleaner. edit_account now
   modifies the form depending on the plugins.
 - minor typos
 - added retrieving email from openid provider
 - moved allow_registration check to a decorator
 - moved check if auth is enabled to a decorator
 - changed openid user registration to go through login first
 - cleanup after merge
 - modified verification emails to use itsdangerous tokens
 - added error handling on bad token, fixed route, and added tests
 - added support for user to change email address
 - added link to login view openid/password in login template
 - updated openid get_user function
 - modified get_user function to take kwargs instead of username
 - no need for user might be email kwarg in check_login_simple
 - added gen_password_hash and check_password functions to auth/__init__
 - added focus to form input
 - made imports fully qualified
 - modified basic_auth.check_login to check that the user has a pw_hash first
 - changed occurances of form.data['whatever'] to form.whatever.data
 - convert tabs to spaces in register template, remove unsed
   templates, and fixed trans tags in templates
 - in process of openid login. it works, but needs major imporvements
 - make password field required in basic_auth form
 - check if password field present in basic_auth create_user
 - modified openid create_user function
 - modified models based on Elronds suggestions
 - changed register form action to a variable to be passed in by the
   view using the template
 - openid plugin v0, still need to authenticate via openid.
 - added a register_user function to be able to use in a plugin's
   register view, and modified auth/views.register to redirect to
   openid/register if appropriate.
 - Modified basic_auth plugin to work with modified auth plugin
   hooks. Added context variables. Removed basic_auth/tools which was
   previously renamed to basic_auth/lib.
 - modified auth/__init__ hooks to work better with multiple
   plugins. Removed auth/lib.py. And added a basic_extra_verification
   function that all plugins will use.
