* clutter/clutter-entry.[ch]: Various fixes to ClutterEntry:
fix code style issues; add documentation for the various
properties; add ClutterEntry:entry-padding property, for controlling
the text padding (until we have style properties separated from
the object properties); notify property changes; free resources
in the ::finalize method; rename clutter_entry_add() to
clutter_entry_insert_unichar(), and clutter_entry_remove() to
clutter_entry_delete_chars() - for bindings and for matching the
insert_text() and delete_text() existing methods; add a getter
method for the max-length property.
* clutter/clutter-entry.c: (clutter_entry_handle_key_event),
(clutter_entry_add), (clutter_entry_remove):
Check if unichar == 0, and if so, return, as it will cause a delete in
the GString.
* clutter/clutter-entry.c: (clutter_entry_set_property),
(clutter_entry_get_property), (clutter_entry_class_init),
(clutter_entry_init), (clutter_entry_set_text),
(clutter_entry_set_max_length):
* clutter/clutter-entry.h:
* examples/test-entry.c: (main):
Added a max-length property whihc limits the length of the text in the
entry.
