Added option to setting plunge depth of Zaxis touch probe.

[CptanPanic]

1. Enabled touch zero button
2. Made default plunge depth max of 0 to prevent problems if pressed and you don't have touch plate setup.
3. Added advanced option to allow modifying to max plunge depth. Personally I use it at 20mm to be able to retract change bit, and just press touch.

I have tested this on my machine.

This is such a great idea. Well done. 👍 👍 🎉

I'll give the code a look over right away, although I can't test it because I don't have a touch plate set up 🙄
