3/28 Vampire class buff, other tweaks!

-Vampire class buff!
--> Can now use wizard oil to better maintain equipment and allow more spell casting (reduces reliance on bloody palm)
-Restore all equipment durability when returning to the main area (similar to how all health is restored)
-Disable durability use in platforming rooms
--> Fixes Inner Fire (kick fireballs) using durability while jumping along with some other movement skills
-Upgraded Unity Engine version
--> Tried this mostly to see if it has any affect on users experience long black screen loads (let me know if not)
