Added MODE7 scroll in all four directions #202

Made scrollRegion in graphics.h take teletext mode scrolls in all four directions. Added x and y parameters to agon_ttxt:scroll method and implement these directions in the scroll method. Everything other than scrolling the whole screen up is slow as it repaints the entire screen.

Tested with VDUU23,16 calls for all four scrolling directions in MODE 7.
