Main points:

-> CONFIG is updated with named constants for convenience.
In Eclipse type: "AntGame.CONFIG." to see a list of named constants
that I've added so far.

-> Ant Builder now works.  In Eclipse: type Alt+Shift+X then Q to
build project using Ant Builder.

Details:

-> Added more global constants to CONFIG file
-> Sub-classed AntGame.CONFIG to AntGameProperties and declared named
constants for existing entries in CONFIG file. The
AntGame.CONFIG.getProperty(String key) method for accessing properties
still works.
-> Added /lib folder with libraries necessary for automation of JUnit
testing using Ant Builder.
-> Updated build.xml
-> New NoSuchPropertyException thrown when the AntGameProperties
constructor attempts to load a non-existent property into a named
constant
