- Renamed former rootPrototype property to hrefRootProperty,

since it defines the root object only as far as href() function is
  concerned
- Add rootPrototype and userPrototype properties that allow to
  set the prototypes for the root and user objects, respectively
- Implement Application.getRootPrototype() and Application.getRootId()
  that allow to get the prototype and id of the app's root node
