Adds a new type of Constant Combinators to the game. They come with a custom GUI to ease the control of LTN signals.

All LTN Signals are supported. Which signals are visible can be adjusted in the "Mod Settings" menu. Any LTN signal placed in an output slot will be visible the next time the combinator gets opened, regardless of the default visibility.
LTN Combinator uses Factorios upgrade feature. They can replace existing constant combinators while preserving all signals.
This mod also adds an new command: Use /ltncopen while hovering any LTN Combinator on the map to open and edit signals without range limitations.

Bug Reports or Requests are welcome and can be posted in this thread or in the Mod Portal.
