#209 FP misbehaviour and inconsistency in 3.0.b2

[Brian Smith]

FP shortcut (Navigate to Peak position) is misnamed as it behaves in 3.0.b2 and behaves inconsistently depending on whether a new peak is selected.
Called for the first time, FP resets the zoom of all windows (bad - why not maintain the current zoom & aspect ratio) and centres the Z of the 3D windows in the, in my case, 15N shift of the 2D window it was called from (OK), but apparently not the 1H shift (unexpected).
Called for the second time on the same (still selected) peak, FP does nothing even if the Z position in the 3D windows have been changed in the meantime.
Called for the second time on the same (deselected & reselected) peak, FP maintains the zoom in the other 3D windows and adjusts the Z (15N) position, but does not centre on the X (1H) position.
In both second time calls the position and zoom of the 2D window is not adjusted.

There seem to be similar issues and inconsistencies with the navigation of the current module when you double click on a peak in a peak table.
