Release 0.113

This release is a bit of a milestone, in that most of the functionality that existed before the engine rewrite is now working again.

Spells, spellbooks, scrolls etc. are all working, plus there are some nice new fetures: wishing wells, gravestones, ethereal foes, clouds, blindness etc.

Feel free to give it a bash - the best way to test is to enter debug mode with "Castor" as the chatacter name. You can then press "y" for infinite wishes, plus you are immortal.

Bug reports welcome.
