As Foretold Implemented

Browse source 
* Final change to card casting code to support as foretold. Removed all of the "Can't cast cards with no mana cost" code from the earlier parts of the casting process and simplified it to just the PlayerImpl::canPlay check and one final check in the main AbilityImpl::activate code after alternative costs have been chosen.
