If the user is not authenticated to the "password" level when they go to change their password, use the old password to authenticate them, then change their password.

* Only check the user's authentication status with the primary once, unless there is a reason otherwise.

* Took some code from the signup page.
* Moved the "open primary auth" window to page_helpers.

* Update network/user to handle two level auth.
* Update tests that check authentication status to check for correct status.
* State machine checks for the correct authentication level for an email address.

* Update the add_email_address page to support scheme.
* Update network.js and user.js to support these schemes.
* HUGE simplification of the Network unit tests.  Vast reduction in number.

* primary - user who is authenticated, owns address, valid cert.
* primary - user who is authenticated, owns address, but invalid cert.
* primary - user who is authenticated, but does not own address.

Required email feels more "correct", still some work to do though for working with expired certs cleanly.

* Changed the state machine so pushing a state to the stack is optional.
* Changed the verify_primary_user screen to have an optional cancel button
* Updated required_email to handle primary verification of unauthenticated users.

It is now possible to sign in to BrowserID using a primary email even if the user is not authenticated to BrowserID.  Needs a lot of cleanup.

* Adding several helper functions to user to check auth status on primary.
* Adding lots of tests.
* Starting to update the required_email controller to work with primaries.

* Defer off to "primary_user" screen and let that take care of the rest.
* in user.js, formatting.

Fixing up a bunch of async problems that were causing the unit tests to error out.  Only call complete whenever jQuery animations are complete.

Upgrading jQuery to 1.7.1.  Fixes a crash bug in IE8 where loading browserid.org would cause IE to restart.

* A lot of cleanup and test adding for handling primary users.
* Trying to genericize a lot of the message names and leave the state machine decide on state.
* Simplifying the ActionsMock in state_machine_unit_test.
* Loads of file renames to make easier to read.

* Hacktastic and minimal tests - loads of tests needed.
