UPDATE: Pre-release update, take 1

As we get ready to leave Early Access we'll be fixing some lingering bugs and satisfying some last-minute feature requests. Here's what's in today's update:

Added copy solution buttons to the puzzle selection UI.
Added new textures for many of the factory blocks.
Added a new tutorial image for the second puzzle.
Added more cases where factory blocks are detached at runtime (specifically, from the "active" faces of sensors and welders).
Added a button for the downward counter to the block type UI.
Removed the survey from the puzzle completion UI. Thanks for all the feedback you've provided during Early Access!
Improved the mouse sensitivity option to have more range at the lower end.
Fixed a bug where you could bind the same key to two or more in-game actions.
Fixed a bug where factory blocks didn't have their symmetry correctly set, making it difficult to create puzzles with solutions that include factory blocks.
Fixed a rendering bug with painted surfaces passing behind holograms.
Fixed a bug where the game could get "stuck" when bringing up the escape menu during a visual fade transition.
Fixed a bug where it was impossible to build on the sides of toggle switches.
