This change moves the responsibility for saving TempData into a filter,
which is registered with other View features. This moves TempData into the
ViewFeatures package.
ActionResults which require TempData to be kept use a new marker interface
which is handled by the filter.
Makes it easier to render a view component from inside a controller. This
makes it possible to implement behavior where an ajax request refreshes
part of a page.
