Issue 1721 android gradient

close #1721

* This ensures the center area is always centered and the scroll bar is shown when necessary.

Make the error messages look right on all mobile browsers by removing the set height of the error message and its contents.

To the #wait, #error, and #delay screens, add the gradients necessary for non-Mozilla browsers.

issue #1721

it's gradient doesn't go all the way down either. We must keep
the backgrounds on #wait, #delay, and #error, since they are
needed to cover the #formWrap background.

the same background of #error is added to #content, so that
even though #error doesn't extend all the way down, the gradient
still does, and it looks correct on Android again.

Nice work on this Sean.  In the near future, we may want to create generic helper functions or move the show/hideHint into PageModule.

Fix a broken require for jwcrypto

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)

add unit tests for __heartbeat__, includes exposing PIDs of all running daemons so tests may do stuff with them (like kill SIGSTOP)

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

Round the timestamp to the nearest 10 minutes.

Not sure why we never caught this because it throws an exception
as soon as you call prepareDeps().
