Mods/TrainCarts/Signs/Waiter

Introduction
Waiters are used to help prevent trains from colliding. Trains will look at the tracks ahead and wait at the sign until the way is clear.

Syntax
First Line: Train/Cart. You can use +train/cart to act as always-powered, or !train/cart to invert the power Second line: waiter. The optional number (without a blank between "waiter" and the number) determines how many blocks ahead the sign will look. Default is set in the server properties file. Third line: (optional) A delay before the train is released when the track ahead is empty.
