Quest Separator: Add Play & Back buttons

[wjt]

This screen previously automatically advanced to the first scene of the
quest after a few seconds, unconditionally.

Increase that timeout slightly. Add a “Play” button. Show a progress bar
over the top of it that follows the timer. Stop the timer on any input
event except a mouse movement.

Add a “Back” button which abandons the quest before it has even started.

Add some margins to the scene as a whole.

Ignore mouse input in the TextureRect which covers the whole scene, so
that the buttons can be clicked.

@manuq I think this is roughly what you had in mind?

(Still to do is to switch this to "Continue" / "Restart". And should there be a "Back" to abandon the quest before it has even started?)

Works great! The button is not clickable but I can use the Interact input action.

Good catch! It's the TextureRect vignette sitting atop the whole scene swallowing mouse input. I fixed that in the latest revision which also adds a back button and puts the progress bar on top of the Back button. (It looks a bit ugly still but it's more like what I'm going for: "button that will press itself" is a familiar pattern on mobile.)

Great! It can't be uglier than the quest separator that I prototyped. This is adding useful buttons to it.
