Change to logging - when logging is disabled, the logging functions are now #define'd to nothing, so the compiler ignores the lines that call them completely, seems to slightly speed up the emulator; note that the logging in vid_table.c has not been changed yet, because this file on my local tree currently contains other WIP changes.
