* game: now all playable calculations done in game simulation, outside real game (no more freeze and ruined games by wrong Nyxbloom Ancient and other cards with wrong replacement dialog);
* game: fixed multiple problems with triggers (wrong order, duplicated calls or "too many mana" bugs, see #8426, #12087);
* tests: added data integrity checks for game's triggers (3 enabled and 3 disabled due current game engine logic);
"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.
removed all references to mage.util.Logging, java.util.logging
transient static doesn't mean anything, since static fields are never
included in serialization
