Update dev

This reverts commit f65ee501.

fixes #1892

Fix the front end tests not completing.

Removing @benadida's change to make the provisioning mock's setStatus asynchronous.  Instead of generating the key whenever the status is set, generate the key whenever the user is being provisioned.  Since the mock uses jwcrypto which must be seeded, seed jwcrypto with some bits.  This more closely matches what a real RP would do.

In the unit tests, any asynchronous calls to provisioningMock.setStatus have been make synchronous.

In user.js, syncEmailKeypair, since jwcrypto depends on there being a seed to generate a keypair, call network.withContext which ensures there is a seed.

The changes to wait for entropy from the backend were not expected on the front end tests.  Now before trying to get a certificate for a primary, make sure "session_context" has been called.

Send the email address to the "check_registration" controller when starting.

Fixes for issue #868 and issue #1517 and styles/assets for issue #1093

@sawyerh - great work on this.  For the future, it is *much* easier to review pull requests that focus on exactly one item.  This would have been easier to review had it been 3 PR's - one for the spinner, one for the iPad update, and one for the button styles - this is something I am working on myself - @lloyd calls me out on it frequently.

Once I updated the frontend unit tests to include the front-end test branch, all ran as expected.  I manually tested the dialog displayed correctly in the iPad sheet program @st3fan produced, Android 2.3.5 native, Fennec Android 2.3.5 mobile phone, Android 4.0 native, Fennec Nightly on Android 4.0, Chrome on Android 4.0, Opera Mobile on Android 4.0, iOS 5 iPod, and iOS5 iPad.

The loader gif still needs hooked up - but it looks great on our buttons.
