From 0ac04776267a1a84724fcccfada12f769f4c315a Mon Sep 17 00:00:00 2001
From: James Haley

Subject: Some reformatting, change of some strings to use DEH_String and
 DEH_snprintf. Implemented proper logic for Shadowarmor that was missing from
 P_GivePower, and added the code for making psprites translucent and/or
 godmode-colormapped in R_DrawPSprite.
