Qualified field context

This feature adds the capability to access the fully-qualified source and destination property paths via methods on the MappingContext:
     String getFullyQualifiedSourcePath()
     String getFullyQualifiedDestinationPath()
     String[] getSourceExpressionPaths()
     String[] getDestinationExpressionPaths()
     java.lang.reflect.Type[] getSourceTypePaths()
     java.lang.reflect.Type[] getDestinationTypePaths()

This is disabled by default (as it can add some performance overhead), and can be enabled via:
DefaultMapperFactory.Builder().captureFieldContext(true)
