Changed Z_PROBE_AND_ENDSTOP to Z_PROBE_ENDSTOP.

Browse Source 
Updated documentation in Configuration.h.
Cleaned up and commented some code relating to Z_PROBE_ENDSTOP.
Separated Z_MIN_ENDSTOP and Z_PROBE_ENDSTOP completely.

// You will want to disable Z_SAFE_HOMING above as you will still use the Z min endstop for homing. // WARNING: The Z MIN endstop will need to set properly as it would without a Z PROBE to prevent head crashes and premature stopping during a print.
