Added:
- automatic launch scan editor option in AMAppController with setter and getter function and a menu option. Tested, appears to be working.
- AMDeferredFunctionCall to AMFileLoaderPluginsCommon.pri ... don't know how we missed this one

Altered:
- fix in SGMFastScanConfiguration2013 was not a fix, it was a bug. The deletion responsibility is with SGMBeamlineInfo class. Done there now.

Removed:
- Took code from scan finished in SGMAppController and moved to AMAppController. If we're not opening scan editors, then the app controller needs to delete the scan when it's done.
