contribution

hi pals, i have a small contribution to make for grx: it's a conio emulation. it still lacks a few features, like cprintf, cscanf (i took them in a hurry from djgpp, but are not working correctly for me), textmode and set_screen_lines (don't seem of much interest for now). feel free to check, use and distribute as usual with free copyrighted software. sincerely yours, Alex Bodnaru
