Window object buffer history support

[GoogleCodeExporter]

The window objects do not support a buffer larger than the window size nor does 
the window keep state after resizing.  A history buffer needs to be implemented 
facilitating a scrollable message window.

For now scroll back is supported for terminals which will keep track of lines 
of text that scroll beyond native terminal scroll regions.  This is a temporary 
workaround which has only been tested in PuTTY.

R50 implements a buffer class which is derived from a window object.  For now 
it overrides the window resize method.  The new method calls the parent resize 
(which clears the window) then reprints windowHeight number of lines last 
printed.

Required still are methods to facilitate scrolling further back in the window's 
history.

The Terminal's buffer subclass does not remove lines from the scroll back list. 
 During verbose debug message window output, the World process slows down 
considerably.  The class should utilize the list and queue ADTs that the World 
code base has been using for a while now.

Scroll-back control functionality added to the terminal buffer object in r198 
and color state of characters added in r200 to support full color scroll-back 
and buffered window redraw.
