1.655 Update - minicopter flying

Edit: Added the electric furnace, click to turn on/off.
Added minicopter flying, this should be pretty close to the real thing but tweaks might be needed so send that feedback.
- toggled in the camera menu (top left), spawns you in the minicopter at terrain/building height below
- no spin up wait to fly, currently ground movement is not included
- press left alt for mouse look, can be customized in the startup input panel
- works in multiplayer and raid mode, someday I'll figure out a fun game mode combining these two things
- fuel usage and damage could be added... waiting for requests on that
Other changes:
- added explosive item number shortcuts in raid mode
- gap spanning floor frames can now be placed through wall frames without red blocking
- added option to update preview images along when updating published workshop items
- lots of changes to multiplayer and camera system code, please report any bugs
Sorry this isn't the industrial update you all were probably hoping for.
Currently I can't access new rust assets because of Facepunch using a newer version of unity. Hopefully I'll find a workaround soon but don't expect a full system, it will be like water hoses.
