Generalize error-display to extended-info.  For every "screen" that is shown, create an extendedInfo and instantiate it.  Remove the "error-display.show" code that was in page_helpers and page_module.

issue #1793

rework __heartbeat__ log message - heartbeat failure is a .warn(), not an error().  the latter indicates an unexpected condition that should never happen in production.  thought here is that the dependee that's failing should have errors() in her log message, and the depener should have warnings.  Also, this gets error messages out of the console output of the unit test.

for __heartbeat__ use an application level global timeout to catch the situation where the other end is not reachable and ensure total wait time is <= 5s (in this case, no 'connect' event is ever emitted)

Handle connection errors and timeouts correctly on heartbeat dependency checks and send error in response - issue #1767

* Make the about code use a PageModule.
* Include the about module in the static_resources instead of including it separately.
* Start the about module when looking at the about page.

- fix a trivial error message formatting bug GH-1278

update BrowserID to Persona in the prove_template email signature - not final but now it is less confusing and matches the url and from address

Change browserid.org urls to persona.org, introduce static.login.persona.org for all static resources.

When a user completes the verification, set their logged in status for the site so a silent assertion can get generated.

* Add countdown until the redirect.

add host parameter back to mysql configuration - fixes accidental regression in commit 3f4368d2

complete_user_creation is less aggressive about deleting the pendingCreation toeken - this allows a user to reload to try to complete email creation if the database is temporarily down

* IE and Opera both try to download all declared fonts, whether the fonts are used or not.  This is an unnecessary performance hit
* Create separate font files. One each for common, dialog, and mainsite.  The mainsite needs italics, which the dialog does not.

issue #1695

* Add a new controller and template - rp_info
* Adjust the screen size hacks to take into account the dynamic height "favicon"
* Add an action to start the rp_info service.

* properly check and escape logoURL and name in dialog.js
* Add some tests ensuring logoURL and name are escaped.
* Print information in rp_info controller.
