fixed various small things I forgot to address in 1.5.2

- Ammo is obtainable in endless mode

- Enemy parry timings have been reverted to the old method of parrying on contact to make it more consistent

- tutorial text reworked to be more readable

- reworked some segments of the tutorial to better reinforce mechanics

- You now switch to exotic ammo automatically if you run out of normal ammo

- resprited Dismember

- exile cloak no longer gives a +3000% damage bonus instead of a 30% damage bonus (oops)
