* new feature: Emblem Cards
Allows match/tournament creator to specify cards to give each player
emblem versions of (or just the starting player for symmetric effects).
Technical details:
- new UI for specifying emblem cards (.dck files)
- available for all match/tournament types
- new class `EmblemOfCard`
- new method `copyWithZone` on `AbilityImpl` (used to make abilities
work from command zone)
- new fields on `GameOptions` and `MatchOptions` for emblem cards
- emblems are granted after mulligans, before first turn (technically
after Planechase starting plane creation)
