Path: Fix g-code arc direction

Browse Source 
Fixed incorrect point orders assigned to g2 and g3 commands.
Add application of `ReverseDirection` property to `ZigZag` cut pattern.
Make default arc direction clockwise(g2) for all cut patterns and layer modes.
Make tool diameter access backward compatible.
