More work on cleaning up debug trace logs. Added getDisplayName() overrides to the Ability & NextGamePhase interrupts so that there's now more contextual info in the output log. You'll now see what game phase is being added/resolved on the stack, and instead of a generic 'StackAbility' entry, it'll tell you what source it's coming from.

Also deleted a few debug output traces that were truly uninformative.
