Work around for slicers producing buggy gcode.

Double Click of Encoder Wheel Jumps to Z-BabyStepping

Fix formatting of SD print time hours above one day

Fix CoreYX / YZ / ZX endstop logic

In the endstop testing section, add the "reverse" logic in addition to "normal" core handling.

In CoreXY/YZ/XZ steppers rotating the same direction gives X movement. Opposing directions produces Y movement.

In CoreYX/ZY/ZX this is reversed. Same = Y, Opposite = X.

----

Fixes the issue where the Y endstop was being checked when moving in the X direction, etc.
