Handle See inside button (#1890)

* Handle See inside button

Import GUI reducers, initial state and middleware (throttle).

Update render to handle state and middleware.

Remove preview mode state and use scratchGui.mode from redux instead.

URL is getting updated, and mode will be updated based on URL. However, the history needs work - it doesn’t work with the modal back.

* Update to latest GUI

This is the minimum version of GUI that is needed for see-inside

* Really remove cruft.
