Increase fine-grained signals for some properties in Flickable
Flickable.at[X/Y][Beginning/End] were being always notified of changes
at bulk. This is can be harmful in performance of QML applications that
will trigger change requests on the program whenever a property is
modified.
This introduces separate signals so it's not a problem anymore.
