LuaAutomation - Basic component implementation

Implements the base code for LuaAutomation, an ATC rail and a punch-operated 'operation panel' as well as interface for passive components.
Changes in advtrains code where neccessary.
Supported passive components are light signals, switches and mesecon switches
