Currently all activities funnel into a common hysteresis mechanism, the result of which is combined with the visually idle state, the result of which in turn drives a UserActivity::Impl. This is a first refactoring towards moving the UserActivity out to WebKit2. Use m_hysteresis only of the impulse activities (plugin evaluation, user input), and flatten the three types of activities (impulse, counted, ViewState) to all directly control a UserActivity. Switch from a UserActivity::Impl to a UserActivity since this will provide hysteresis for media activity.
