Add more monsters being capable of spattering the floor with blood.

Should we use the same reasoning for which monsters' corpses vampires can feed on? Currently they can also draw blood from insects and worms, which seems a bit odd. But everytime we restrict the sources of blood further we make vampires (un)lives a bit harder.

For comparison: Currently vampires can draw blood from all monsters with chunk type clean or contaminated. This includes, among others, royal jelly, death cob, devils, skeletons (!) and a whole lot of other demonic or undead beings. Blood spattering, on the other hand, only works for monsters that have either M_WARM_BLOOD or M_COLD_BLOOD set, and this is the case for a subgroup of natural and holy creatures. I'm in favour of this change, and unless someone else has good arguments not to change this, I will.

Also fix hungry vampires leaving blood stains.
