Removed XES and XAS scan actions and related stuff from REIXSAppController.
Removed allControlsSet from REIXSBeamline, replaced with addExposedControl type setup. Removed REIXSControlMoveAction stuff from REIXSAppController. Added a hack so Dave could get special access to controls for control move actions with command line argument.
Fixed minor merge conflict where two functions had been added to REIXSBeamline
