update the http_forward module to allow global request timeouts to be set, use this to implement a 15s upper bound on requests for declaration of support in development.  This should fix unit tests

Change the order of assertion generation to be after the user is asked "is this your computer?"

Update remaining reset_password test to deal with new flow when the user confirms the address.

* This fixes a problem where it is possible that a user takes more than 2 minutes to answer, making the already generated assertion invalid.
* A lot of general cleanup of the state machine.
* Push all post email selection flows to a new state, "email_valid_and_ready" which decides whether to ask the user the computer ownership status.
* Assertions are generated after the "is this your computer" is asked.
* doEmailChosen is replaced with doGenerateAssertion - there were multiple calls to generate an assertion, not very DRY.
* Fix a problem in network.js where a user who completes user registration should be marked as authenticated.
* rename email_chosen.js to generate_assertion.js to clarify its purpose.
