roll back ace
Deleted leftover services_common.dart in lib.  Moved ServiceActionEvent from utils to services/services_common.dart (exported by services).  Added "as analyzer" to analyzer.dart and removed "as common" from services_common import to make services_common classes first-class and shadowed analyzer classes second-class.
