Protection scrolls don't bypass MR

[CamDawg]

From BD; the various protection from X scrolls can be blocked by MR. Also makes one more minor change (from devSin) where the unidentifed name for Protection from Electricty is changed from "Scroll" to "Protection Scroll" for consistency. This affects scrol03, scrol04, scrl05, scrl06, scrl08, scrl09, and scrl15.
