1.618 Update - Medium Battery and Electric Usage System

Sorry for the wait, the new battery power usage system was a bit more work than expected. In Rust it certainly has some weird aspects that are hard to replicate, like disabled outputs on timers and memory cells adding to usage. Everything else seems accurate but let me know if not. I'm sure more adjustments will need to be patched in soon.

- added medium battery and updated battery panel UI

- added extra switch inputs for toggling it on and off

- added RF pager list, see any active frequencies

- laser distance is properly set on placement now, click it to check and set distance

- fixed a bug with saving wired connections after saving the scene as a json file

- placement rotation now saved separately when switching from build/place menu

- fixed bug preventing using scroll wheel in file list

- fixed wire highlight material when using MSAA

- camera speed controls now affect 3rd person mode

- added mesh collider for shotgun trap, easier to click around

- fixed some pink materials


Some things were patched in-between 1.617 and 1.618:

- fix for dark water bug

- merging and copying includes any wires

- fixed align bug with wires

- audio alarm button was spawning wrong prefab
