Add final (slightly modified and extended) part of patch 1295927 (vga accuracy) from keith. Add (modified) bug/patch 1241142(ansi emulation updates) from moe. Add fix suggested by vasyl to fix MyChess. Corrected some missing parts in these patches. (Missing update nbrows in dev_con.h). Implemented a writebuffer to workaround the CR/LF issue. Let's hope everything still works
