Rename MIN_COLUMNS to MIN_COLS for consistency with the COLS variable

Browse Source 
Also define WIN_COLS and WIN_LINES: the current version of Star Traders
will only use this number of lines and columns in a terminal window.  All
calls to newwin() need to have COL_OFFSET and LINE_OFFSET added to the X
and Y starting positions to make this work.
