fix bz130 - muse: sliming and fire horns

Browse Source 
There was no check for being capable of using items when an attempt
to cure being turned into green slime picked scroll, wand, or horn
of fire.

Also, implement a 'TODO' in the same section of code.  Monsters
can enter fire traps to cure themselves from slime.  I made that
be for monsters smart enough to use items too, even though there's
no actual item involved.
