Changed name of computer.bell to computer.beep and added option for frequency (20 - 2000Hz) and duration (0.05 to 5 seconds).
Forcing computer to sleep for the duration of the sound.
This is uncomfortably close to what should go into a sound card, but... it's just too nice not to have it in by default.
Somewhat less broken besh, but something's still not right...
