Bridge split factor

Hi

Working over few bugs in Bridge I realize that not always we need such a high resolution in bridging detail provided by the automatic splitting algorithm implemented in it.
And the fact that in most cases tunnels are hidden from the actual models it can be good to fine tune its detail level so it can be less or perhaps more?, because there’s everything in this world 😛

So I add a slider to control that possibility if user wants too, but the default will be the automatic detail estimation.
