Cloak and Dagger

Invisibility modified to be nullified when the potion effect "exposed" is also applied. By default, attacking adds 5 seconds of expose. This makes invisibility stabs more dependent upon hit-and-run without negating the utility of long invisibility potions, as would be caused by directly removing invisibility on attack. Not to be confused with the expose when your posture is emptied.

Tweaked default items slightly. Again. This is probably the last time I'll touch the default armor data.
