Title: [fixedToolbar] Move page handlers to the widget prototype level and...

...attach them using ._on()

Please have a look in particular at how the old handlers assumed that ```this``` refers to the page which triggered the event, whereas in the new code, ```this``` refers to the widget and thus the page which triggered the event is assumed to be the closest page, i.e., ```this.element.closest( ".ui-page" )```.
