Megatronics 3 servo pins

Issue #1504 – K8200 Z_ENABLE_PIN

- K8200 uses a non-standard RAMPS with Z_ENABLE=63 ??
- Assuming from previous input that 3DRAG is the same.

The `float` keyword should not be on these vars because they conceal
the outer vars, preventing them from obtaining known values before
being passed in `set_bed_level_equation_3pts`. Possibly related to
`Z_RAISE_BETWEEN_PROBING` not functioning.

Merging latest upstream changes

Fixed how stepper ISR figure it out when the head (extruder) is going to
Min or Max direction.
Added Homing to Max Endstops.

Compiling errors with 4 Extruders defined and Viki 2 Implementation

Multi-line G-code commands

- Naive implementation, assuming the data sheet pin numbers correspond
to Arduino pin numbers.
