grid: attributes now track whether we've set a foreground/background color

Browse source 
This means we don't have to explicitly set the foreground/background
to the grid's default colors whenever we reset/clear a cell, and we
can instead simply memset() the entire cell to 0.

This also means the renderer has to get the default color when
rendering a cell without a foreground/background color set.
