cx16: removed monochrome modes from gfx2 (use monogfx instead). New screen mode numbering!
programs will now be a lot smaller than before if they use gfx2 (or monogfx if they were only using monochrome drawing) monogfx also fixes some drawing errors with small horizontal lines, and stippled vertical lines.
