Added a latched Relay to cutoff switch, improved autocutoff

I guess it's sort of a rite of passage to pull the vise back when the auto feed hasn't gotten completely tripped yet, but after one baptism, that was enough.  I'm sure some of you never forget, but I get excited looking at the rock.... and am likely to forget.   And it is minor-ly dangerous to have the saw start up unexpectedly.

Simple way to cure this, you need a 120v relay, and a momentary push button switch, a few wires & terminals.  Google a latching relay circuit.

Basically the push-button momentarily energizes the relay, and the relay back feeds to keep itself closed (latched).   That back feed is routed through the cutoff switch, so if the circuit is broken the power is now cut and it won't restart  until the push button is pushed again.  ie no start if I pull the vise back and the cutoff switch isn't completely tripped.

All fits easily inside the lortone motor box up front...  and no more oil showers!
