Subject: Particle images are now reference-counted properly. Avoided attempts
 to load "data/graphics/" when a monster or equipment piece has no sprite.
 Error placeholder is now used when attempting to load a sprite definition
 file that doesn't exist.

+	* src/monster.cpp, src/player.cpp: Avoided attempts to load "data/graphics/"
+	when a monster or equipment piece has no sprite.
+	* data/graphics/particles/cookingfire.particle.xml: Removed some particle
+	properties that did nothing because they were misspelled.
