[kovarex] [0.17.4] Undo does not restore circuit connections

[jmurrayufo]

Problem: Pressing ctrl+z (Undo) after removing an entity with a circuit connection restores the item, but not the circuit connections it had (even though the other entities are still correctly placed).

Expected behavior: Undo should restore affected entities to their previous states.

Tested on: 0.17.4 with Combinators, Lamps and power poles in various configs. Hand removing items, cutting the item, or deconstruction seems to all effect Undo the same way.

I've attached a quick save to demo the bug as well.

Thanks for the report. It wasn't trivial to do, but undo will support circuit connections in 0.17.7

Thanks for the fix! Ctrl+Z is a game changing feature for my clumsy game play, and this was the only part of it that I've found that didn't seem to work right.

You guys are awesome!
