* apply regex to change public copy constructors to protected
* cleanup code using now protected constructors
* fix manaBuilder weird casting of Mana into ConditionalMana
* Fixed issue with UntapTargetCost
The target was allowed to actually target, so things like Halo Fountain wouldn't work on creatures with shroud.
UntapTargetCost also keeps track of the permanents which were untapped, in case those are needed.

"b" + "r" now changed to 'b' + 'w'. It's more straight-forward, and may cause perfomance improvements - character primitives allocation is faster and less expensive than string creation.
