Added onClick listeners and handlers for ToDo
Added action bar buttons to 'edit' activities

Also returned the default menu to the Main activity
Updated 'NewMovie' to match 'NewBook'

Also extracted the code that paints the genres on the layout into a
method.
Split 'getBoovie' into tow methods

Also changed the way how the 'Edit' activity is being called and started
working on the code that shall get the selected book and display it in
the 'Edit' activity. For now it seems that I'm getting some incorrect
data from the database or something.
