Adjustable opto holder with space for the wires

The default opto mounting brackets for the Prusa Mendel don't mount opto stops very well. Or at least not the ones I have, which have wires coming out the back.

I like how Geoff has the orientation, but don't want to bend the leads on the opto stop.

This allows the opto holder to be mounted flat on the bracket with screws and allows the leads to feed down without bending. It is also one piece to mount the stop.

I used springs between the opto stop and bracket so I could make fine
