fix #6187 - attempting to eat inedible artifact

Browse Source 
Rearrange the tests for edibility of non-food so that touching an
artifact won't happen unless the object could be eaten.

Add a bit of bulletproofing for rust monsters trying to eat a
rustproofed item and spitting it out.  Wishing for rustproof iron
ring, cursing it, wearing it, and attempting to eat it as a rust
monster would remove the rustproofing and spit it onto the floor,
ignoring the cursed state as far as taking it off goes.  That was
an issue in 3.4.3 and probably in 3.6.0, but in current code the
'rustproof' part of the wish would be ignored for an item which
isn't subject to erosion damage, so hero-as-rust monster will
successfully eat the ring instead of spitting it out.
