Added the ability to add and remove scan axes from the new AMStepScanConfiguration.  Changed AMScanAxisRegions from members to pointers to allow for polymorphism when doing EXAFS.
Added a copy constructor to AMScanConfiguration.  How it went on this long without one is a bit scary since this may cause unintended issues.
Got AMScanAxisRegion fully database ready.
Registered AMScanAxis and AMScanAxisRegion in AMDatamanAppController.
