1.627 Update - accurate foundation proximity check

- improved foundation proximity check system
For those unfamiliar, this red blocks foundations while placing if too close to others to prevent wall stacking. Before this was my best guess at replicating what was happening in Rust. Now I have access to the actual code so it should match up perfectly. It can be disabled using free place under placement options.

- added the big electric red button that allows passthrough for 5 seconds

- changed how the TC radius tool works, allows for changing modes (place/build) and it stays toggled

- added "on surface" checks for the heater, dropbox and a few more large deployables

- fixed roofs not allowing for placing floors above in both directions

Expect another update next week with the vehicle lift.

Oh and the electric upgrade DLC is currently on sale which supports continued Fortify development.
