Hiroyuki Ikezoe 2639916d7d style: Set the important rule change flag when a newly important rule is inserted.
Without this change an assertion checking IsInStyleRefresh() in
EffectCompositor::PostRestyleForAnimation will be hit when we call
FindAnimationsForCompositor from RestyleManager::DoProcessPendingRestyles
that will be introduced in a subsequent commit in this series.

I wrote a crash test which causes an assertion in KeyframeEffect::CanThrottle()
without the subsequent commit, but we need more work in display item stuff to
make the assertion won't happen (bug 1508466).
