Merge branch 'lisp' into master, split off branch 'python'. ...

From now on, the master branch will combine both implementations. Each language
should use its own branch for development.

Deleted python directory, preparing for merge into master branch.

More work on character.py, preparing for lisp/python merge

More work on util.lisp, changed license to MIT.

character.py more or less finished, added item.py

Changed the input macro to take any number of input variables

Added CharacterClass and Race classes

Further work on atlantis.lisp and util.lisp

Expanded player.py, slight other modifications

Started on atlantis.lisp, util.lisp

First commit to the Lisp branch. ...

Originally I had wanted to write Atlantis in Lisp. Due to various factors I
decided to do the main implementation in Python, but I want to try in Lisp
anyway.

Minor bug fixes, started on player.py

Merged branches 'applicative' and 'applicative-remodulate'. ...

The basic structure of the ATL interpreter now stands and (sort of)
works, still some bugs though. And obviously plenty of features left
to add (currently implemented: define-place, description, neighbours).

Ready to merge back into master.

Reorganized the modules, move DefineCommand into new module define.py ...

This avoid circular dependencies.

Various bugfixes on the interpreter.

Wrote most of the interpreter, need to find bugs now to get it to work.

A lot of work on World and the interpreter. ...

This is the applicative branch - I cut out the OptionCommand class, using
method calls to stored function names for options instead.

Added the banner, wrote interactive starting mode.

Significant progress, especially in place.py and parser.py

Wrote example.atl, the reference file for the Atlantis language. ...

Started on main code.

First commit of Atlantis to git. ...

Not much to see yet.
