Added x and y coordinates to Space.
Added x and y coordinates to Space.

Time for a Java rant:
I initially threw these four helper functions
( getX(), getY(), setX(int x), setY(int y) in Space
to work with absolute positioning in the Board class.
Little did I know that these four innocent little helper
functions must have overridden *something* in the inheritance
tree, completely destroying my drawing code.
Three hours later, I threw away my work and started again,
and found these little guys messing me up.
Thanks, javac, for not bothering to tell me that four functions
not marked with @Override were overriding something.
That's kind of the thing I would like to know about.
