More stuff for the tutorial:

- Enhanced handling of spellbooks and artefacts. 
- Feature descriptions now cover altars.
- Added monster descriptions (out of depth and brands).

Also: 
- space-only inscription counts as no inscription
- ring of teleportation autoID's if no teleport randart

In my last commit I forgot to mention that the 
descriptions were suggested by Richard Gould, and
I'd like to give credit where credit is due. :)
