Fix problems with "position" and "selection-bound" change notification

Browse Source 
Added a "selection-bound" notify on clutter_text_clear_selection as it
changes the value.

Added utility function clutter_text_set_positions, in order to
change both cursor position and selection bound inside a
g_object_[freeze/thaw]_notify block

Added g_object_[freeze/thaw]_notify in other functions that changes
both cursor position and selection bound
