Re-order cards.json with starting ID of 0

* This simplifies card to face ordering logic between cards.json and
faces.json (faces.json IDs start at zero). Hopefully this helps to
avoid future bugs!

* Introduce CARDS_COLLECTION, MIN_COLLECTION variables;
CARDS_COLLECTION is the number of cards loaded into memory count,
whereas MAX_COLLECTION & MIN_COLLECTION serve as buffer sanity
checks.

Ultimately, this serves to allow us to add more cards to the
database without recompiling, provided that we don't go over
MAX_COLLECTION (set arbitrarily at ~220 for the moment)

* Improve sanity checks done in CardCollection:

a) Remove DEBUG preprocessor checks (we now do these sanity checks
regardless of DEBUG or RELEASE build types).
b) Additional checks
c) Clean up error messages a bit
CardHand: Introduce MIN_PLAYER_HAND variable

* Remove DEBUG preprocessor checks (we now do sanity checks
