Arti's Characters and Followers 2.1

Added two characters and two followers:

• Hisui (Tsukihime) (1/5)
• Mech-Hisui (Melty Blood) (6/7)
• Crummy Wizard (Dota 2) (Horn: Anti-Mage saying... the line. Contains profanity.)
• Squapes (Final Fantasy XIV (Horn: BEHOLD, FRUIT)

Also included: a custom category for this pack's followers. I'll release them all individually (and a clean version of Crummy Wizard) if there's any demand at all, basically, lol
