Religion marks, room spells, trophy, snow

- Most religion marks now have standardized chance, improved if your deity patrons your race, class or clan. Official religions trigger a bit less often than cults, but are more powerful. - Some religion effects got improved or revamped, help articles are updated - Battlerager's trophy is updated: can now make a poncho from any bodypart, but requires a bit more preparation - All hostile room affects (narcotic mist etc.) are now standardized: won't trigger on your group members, your clan members or their followers, always trigger an additional time when an enemy enters a room (so it'll work more often now) - Berserk duration and effect are slightly updated - It's snowing during winter -- feel free to play snowballs just for fun! - An old wizard somewhere is now selling a couple of very helpful potions - Battleragers now auto-remove magic items if those got equipped somehow - Multiple bugs are typos got fixed -- as usual, thanks to everyone who helped!
