Add delays to cleanup actions since scaler seems to frequently end in
bad state (i.e. not properly reset for continuous monitor).
Moved `REIXSXASScanCOntroller` from `AMRegionScanActionController` to
`AMStepScanActionController`

Re: Issue #666 and #649
Almost as if by magic, removed a `this` and solved a seemingly
unsolvable crash bug.
Add min/max limits to `energySpinBox` on spectrometerControlEditior to
enforce existant `eVRangeMin`/`eVRangeMax`, in the
spectrometerCalibration class, based on selected grating to avoid
commanding the spectromter to move to unreachable energies, as the limit
switches do not require further feild testing.
