This commit adds support for regeneration (both regen and deregen) and
minions (for both goodguy or badguy - or both at the same time). It also
adds tests to ensure correct code workflow.
Adds attack, defense and damage modifiers for both "goodguy" (self) and
"badguy" (target) as well as a handler for goodguy/badguy invulnurability.
Modified the battle calculation to not recalculate if noone does damage as
long as at least 1 buff is active. This prevets infinite loops.
This commit introduces basic buff handling: Adding buffs, removing buffs,
expiring buffs. The Battle procedure controls the buffs and activates them
every round, expires them one round per round and removes the buff if the
number of rounds left is 0.
The BattleTest suite tests for the correct sequence and the correct
messages.
