[gedit] Do not emit cursor-moved when we are inside an user action

[Paolo Borelli <pborelli src gnome org>]

    Do not emit cursor-moved when we are inside an user action
    
    This prevents wasting time updating the statusbar label when doing
    many inserts/deletes as part of an action. The signal should still
    get emitted in the end in response to the buffer::changed signal
