mach3 soft limits

[Kitwn]

My simple brain tells me the sensible order of events is:

1) Install limit switches. This prevents any damaging crashes from here on.
2) Set up homing. Separate switches if you must but using the same limit switches works for me and reduces cost and complexity.
3) Set up soft limits. This prevents any annoying, unwanted hitting of the limit switches and allows you to jog the gantry out of the way by simply letting it run to the soft limits.

As Jazz says, soft limits have no meaning until the gantry is homed so 1 & 2 must come before 3.
