New game modes, bug fixes in primitives, improving AI, new planeswalkers type rule

New rules based on vanguard, 3 new random game modes, one is tribal and one uses any card in the game.

Several corrections and bugs fixes. Cards with x in their cost and that can target any player used to crash the game.

Teaching AI new things and changing values of efficiency.

You can have multiple "Jace" planeswalkers, you can't have two of the exact same name (no two Jace, the mind sculptor).
