Release 7 -- Combat Update

This update introduces an active skill component for items.

Features
Active skills cost energy based on their JSON definition
Active skills use colors based on their JSON definition
Active skills use flags in their JSON definition
The following flags are supported: unblockable damage, blockable damage (cannot hit walls), movement, and "require space" (if a move skill uses this, the unit may be running; without it, they may be leaping)
Active skills use the message log to display information about the item and skill
Fixes
None
Finagling
CombatProcessor now supports hitting many units in one action
A few more items have been added to test the active skills
