A minor update to add some bug fixes and improvements.
- Added a little more info and a note to the netmap manual to explain it's not available in all OS versions, same with the telnet one.
- Added more info to the devices' manuals to make it clearer that a telnet connection needs to be established with them to use the commands.
- FIXED: the player could go around some of the vertical pipes in level 14.
- FIXED: the lift could still be climbed in the middle position.
