* moved deck saving to end of match. It now only saves when you've actually completed a game.

* added additional meta data for decks when saving them back to file.
  - decks saved this way now are split into three regions: creatures, spells and lands.  It's more for a visual sorting if a
     player wanted to look at the deck outside of the game.  It does not impact the deck loading negatively at all.  It may
     increase performance in cases where the deck was previously defined using the canonical names of the cards as the numeric ids
     reduce the work done when looking up the cards by name.
* modified ManaCost toString method.
* added toString method for ManaCostHybrid ( possibly make ManaCostHybrid a subclass of ManaCost)
* added additional operator overloading for ManaCost for printing to cover ManaCost when it's a pointer as well as a copy
   ( TODO: might want to check if making usage of ManaCost as a copy as opposed to a ptr is really necessary in most cases. )
* added alternate version of "trim" to handle trimming temporary strings as returned by things like ostringstream.str().
 - This was necessary since the PSP compiler doesn't do the necessary adjustments for those types of calls.
