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)
