Replaced all instances of "her or she", "him or her", and "his or her", with "they", "them", and "their", or sometimes "that player". Updated verbs where appropriate.
* Fixed Rankle's triggered ability
Any number of available modes can now be selected, including zero.
* Update AbilityImpl.java
* getTargets now returns empty Target for null Mode
Reverted null Target check changes in StackAbility.
* Update HumanPlayer.java
* K'rrik fixes, payment for triggered abilities
K'rrik's Phyrexian ability is now handled separately from actual Phyrexian mana costs. It can now be used to pay for triggered abilities like Extort.
* K'rrik tests added
Tests include:
- only usable by 1 player
- usable with activated/triggered abilities
- usable as an alternative to true Phyrexian mana, getting around Trinisphere
* Pay X abilities - fixed that it spends all available mana pool instead only needed;
* Pay X abilities - added support of interactions with other X effects like Rosheen Meanderer's mana usage for "pay X to prevent";
* Rosheen Meanderer - fixed that it can't use mana for "you may pay X" like Flameblast Dragon's effect (#5206);
* Devs: added support to use VariableManaCost to pay X in code (without generic's workaround, use ManaUtil.createManaCost to generate cost to pay);
10 or so initial planes that (mostly) have been tested, no phenomenons as yet and no modifying yet of chaos rolls. Also no support for a user to be able to set if it is planechase (able to do so via the cheat button).
* Final change to card casting code to support as foretold. Removed all of the "Can't cast cards with no mana cost" code from the earlier parts of the casting process and simplified it to just the PlayerImpl::canPlay check and one final check in the main AbilityImpl::activate code after alternative costs have been chosen.
