KlickyNG for Voron V0.2r1 niggles

[bozzzzo]

• Cowling hits the XY joint, some material needs to be removed and maybe some material on the XY joint can be shaved off, too. For now I tested modifying the cowling so that I get same motion as with Klicky "classic", need still to check how much additional space the wires will need.
• Probe "longest" is wobbly even when using two N45 magnets for the third magnet. Solved by deepening the hole for the third magnet on the Cover to 2.5mm, so that the third magnet is partially not covered by the cover.
• Probe "longest" has to be shortened by 3.5mm to bring the switch in axis with the nozzle.
• Probe longest is missing the helpful arrow for the microswitch orientation :)
