Settlement SGTM: Efficient Time Management

[shulme]

This one is pretty simple. Would add a holotape that uses the SGTM [set global time multiplier] to 1 [default], 2, 3, 4, 5, or 10. This makes the game run faster, letting waiting or settlement manufacturing equally go faster. One possible limitation would be for it to only work in settlement boundries, but up to you.
