OpenCS settings

I would like people to try it out and provide feedback comments please.  There are some debug statements still in there, please ignore them ;-)

EDIT: now integrated with existing settings code
EDIT2: subview settings implemented
Even the existing settings implementation before any of this has predefined window sizes.  This isn't something I've introduced.  In any case, the option is not visible nor presented to the user unless one really looks for it.
