- Refactored the card-specific AIs implemented so far to its own class SpecialCardAi, will consider moving other card-specific hardcoded logic there later.

Browse Source 
- Implemented rudimentary AI logic for Necropotence and Yawgmoth's Bargain, could use improvement but should be fine in typical situations.
- Promoted Necropotence and Yawgmoth's Bargain from RemAIDeck to RemRandomDeck.
- Propagated the SA parameter to checkLifeCost (and closed the previous TODO associated with that), was also necessary to support the Necro AI logic.

/**
* Special logic for individual cards
*
* Specific methods for each card that requires special handling are stored in inner classes
* Each class should have a name based on the name of the card and ideally preceded with a
* single-line comment with the full English card name to make searching for them easier.
*
* Class methods should return "true" if they are successful and have completed their task in full,
* otherwise should return "false" to signal that the AI should not use the card under current
* circumstances. A good convention to follow is to call the method "consider" if it's the only
* method necessary, or considerXXXX if several methods do different tasks, and use at least two
* mandatory parameters (Player ai, SpellAbility sa, in this order) and, if necessary, additional
* parameters later.
*
* If this class ends up being busy, consider splitting it into individual classes, each in its
* own file, inside its own package, for example, forge.ai.cards.
