[AFC] Implemented Share the Spoils (#8583)

* Preliminary implementation of Share the Spoils.

* Added tracking of cards in exile to MageTestPlayerBase in order to help with testing of cards such as Share the Spoils which put and take cards out of exile a lot.

* Moved Share the Spoils to the correct set list.

* Fixed bug with using ’ instead of ' for card text.

* Add method to assert number of cards exiled into a specific exile zone.

* Further implementation of ShareTheSpoils and it's tests.

* Fixed a bug in the calcualtiong of exileNUmber. (I misunderstood what the copy() method was for)

* - Added a watcher which should limit player to only cast the spell once per turn.
- Fixed the tests to run properly (using .LOST instead of .LOSES for the GameEvent).
- A bit of cleaning up of the class

* Updated tests and card to capture both conceding and losing the game through other means.

* Further implementation. All parts are working (though not correctly).

* All pieces are now working. But, both the spend any mana and exile a card off the top of library activate when ANY card is played from exile, not just one exiled with Share the Spoils.

* Replaced changed how I move card from top of library to correct exile zone. Instead of using moveCards() and moveToAnotherZone(), I am not using moveCardsToExile().

* A new card is now properly exiled whenever one is played with Share the Spoils

* Moved inner class out and passing exileId as parameter instead

* Updated text based on comments

* Added several more tests

* Made changes to how exileId is handled based on comments

* Made changes based on comments

* Further changes based on comments

* Add a few more tests (will have to fix them once the exile zone issue is fixed)

* Added workaround for #8706

* Get most of the tests working

* Simplified cardId handling

* Reformat file based on comment

* - Added setStrictChooseMode to all tests
- Properly using checkPlayableAbility for all checks where things can't be played/cast.

* Fixed a missing getMainCardId call that made difficult cards unplayable

* - Simplified handling of casting only once per turn. I don't see the point to keeping the MageReference object. using a simple boolean instead
- This also fixes a bug where multiple cards could be played in the same turn.

* Fixed test for difficult cards.

* Reworked spend mana effect based on Dead Man's chest

* Added a check again a null watcher

* Fixed typo in checkManaSpendingForOtherExileSource

* Fixed tests to use proper checkPlayableAbility syntax.
