More Circuit Signals (Updated for 1.1)

This is a mod that adds more circuit signals for easier tracking of variables. This mod is not mine and the original was made by Lockyy. You can find the original at https://mods.factorio.com/mods/Lockyy/more_circuit_symbols. All I did was update the version in the info file. All credit goes to Lockyy and I will remove this mod if he decides to update it himself.
