🚧 Add insulator wall (#840)

* Stash insulator prototype

* Fix automatic wires when placing non-powernodes

* Implement requested changes

Stopping lightning has yet to be added.

* ❤️

* Implement lightning absorption

* Visually distinguish insulated power lines

* Stop lightning infront of wall

* Highlight insulators instead of recipients

* Attempt to implement requested changes

* Implement requested changes

* Remove spaces between if and (

* Snap lightning to insulated blocks

* Update bundle.properties
