Add context for altering Poker Hands

[DigitalDetective47]

Adds a new context, used when poker hands' values are changed (primarily through being leveled up). This is different than context.using_consumable, as it also affects other ways of leveling up hands (e.g. Space Joker).

if context.poker_hand_changed then

context.old_level, context.new_level
context.old_parameters, context.new_parameters -- only contains scoring parameters that were changed
context.scoring_name, context.card
