The destroy signal handler is kept connected despite the NotificationMessage
being destroyed, which leaves dangling NotificationMessage objects that will
be mass destroyed when the Notification object these depend upon is finally
destroyed.
Depending on the amount of accumulated NotificationMessages, this may lead
to temporary freezes or other more funky issues when recursion limits are
hit.

When loading several animations at the same time, the last call
overrides the result for all of them.
This commit caches all animations separately based on the source's
schemas.

We currently will always allocate the user list's preferred size, so it
will grow indefinitely and never scroll; limit the height instead to
get the desired scrolling behavior when necessary.

When the user successfully types their password, we should hide
the spinner from the button well right away, so it doesn't
consume resources until reset (which may happen significantly later
if the user is vt switched away)

The code previously tried to stop spinner after it was hidden, but
due to an incorrect check was only stoppig it after it was shown.
Also, it was only stopping after hiding due to an animation, and
failing to stop it in the non-animated case.
This left the spinner hidden and running while VT switched away
from the login screen, only stopping when the auth prompt was
reset when switching back.
