Edit readme/project.clj. Some standalone function

Began incorporating some functionality to allow the program to run as a
standalone game.  That is executed via lein run and then interact with
it via simulated years.

Completing this stage will require: a program loop in core.clj and
seesaw dialog boxes to provide a window onto inner program state.

updated readme and project.clj files.  added github link and removed
cruft
