* Create common .submit > p and .tospp CSS declarations.

* 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.

no longer used in storage.js.

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