Annotation: the class has been passivized. It's only a data container now,
  no more active manipulation of events/paints.
PageViewAnnotator: this class has been created to handle creating annots.
  PageView creates its 'Annotator on demand. The annotator parses tool
  definition from the 'tool.xml' file.
  The Annotator internally uses AnnotatorEngine(s) to react to mouse events
  and the annotation is created when the job is really finished.
Page: added a (maybe temporary) NormalizedPoint to complement Norm..Rect.
PageViewUtils: removed PageViewEditTools and cleaned up header.
conf/: added a debug option for showing annotation boundary while creating
  one and added a temporary 'debug' toolbox in the config dialogs.
