Patch 0.5.1.0

This patch adds a bunch of new abilities! [list] [*] Allegiance [*] Exodus [*] Flesh and Blood [*] Hellfire [*] Holy Hand Grenade [*] Reflector [*] Temptation [/list] I'll leave what they do up to you to find out! I've also shuffled around a few upgrade costs and added cooldown as a reward to all active abilities.
