Renishaw HeadAxisAngleinversionEnable setting

The Renishaw I++ server allows to define the path that the head performs during the movement of the A and B axes.
Based on the value of the variable HeadAxisAngleinversionEnable (true or false), the server will pass the angle A from positive or negative (without rotating the B axis) to optimize the path of the head.

The inversion of the angle A can only be set by Renishaw Server and cannot be controlled run-time by Arco: therefore this behavior should be decided priory considering that the change on existing programs could alter the path of the head and lead to unexpected collisions.
