Removed:
- SGMXASScanConfigurationViewer.ui
- AMScanConfigurationView.ui (note this is not related to the proper
AMScanConfigurationView class)
- AMSamplePositionViewActionsWidget.ui
- AMJoystickTestView.ui
- AMJoystickTestView
- AMGenericLinuxJoystick

Altered:
- REIXSAppController - Removed all references to AMGenericLinuxJoystick
