RedstoneCONTROL - Client PC [WIP]

--[[

RedstoneControl - Client PC

The client PCs connect to the main PCs and collect information from them.
They also possess Advanced Monitors, so players can use them without opening a GUI

PING is given by the server, and updates the clock.
Lift Control is handled by Advanced Monitors, player just clicks the floor he wants the lift to go to.
Lift location is handled by messages recieved from ServerPC.
