Omit on SIGI & (XR/YR/ZR) Rotations

Depending on the context:

Omit 0, 1 or 2 Sigma Iobs data from the Fourier Map Calculation.
XR, YR & ZR buttons, when pressed allow for the rotation of the molecular display in order to (de)select clickable atoms.
In the Contour map plot mode, only ZR is active. The default rotation about Z is 10 degrees.
