LibraryManipulator is now merely a notifier

Browse Source 
Originally `LibraryManipulator` was an abstract class completely decoupled
from `Library`. Its `addBookToLibrary()` and `addBookmarkToLibrary()`
methods could be defined in an arbitrary way. Now `LibraryManipulator` has to be
bound to a library object, those methods are no longer virtual, they always
update the library and allow for some additional actions via virtual
functions `bookWasAddedToLibrary()` and `bookmarkWasAddedToLibrary()`.
