Mod support

Modded rails should work out of the box, as soon as updating FARL to at least 1.0.6

There are 2 remote functions to tell FARL whether it should raise on_robot_built_entity/on_robot_pre_mined events for a specific entity:
- remote.call("farl", "add_entity_to_trigger", "entity-name")

If FARL should no longer keep on raising the events use this command (probably never):
- remote.call("farl", "remove_entity_from_trigger", "entity-name")

To make it work just add FARL as an optional dependency in your info.json and do the remote.call in on_configuration_changed.
FARL stores the names in global and only removes them if the interface is used or the entity doesn't exist anymore (checked in on_configuration_changed)
