wumpus-basic

Copperbox revision 1766.

I've worked through the demos and they should all run now.

Also, I've done some tidying up of Basic.Graphic removing the functions localLG and lgappend. They can be recreated with Applicative notation slightly more verbosely, so not having them as functions is something of a loss, however, I felt they were adding more "concepts" to the Graphic.Base API so that swung the balance in favour of removing them.
