Title: De-duplicate session flash features.

With a proper FlashComponent and FlashHelper we don't need to have a duplicated set of features in the Session object. This change also unifies the keys SessionComponent/SessionHelper and FlashComponent/FlashHelper use so no matter which interface you use, everything plays nicely together.
