* gtk/gtktreemodelsort.c: more changes in an attempt to get
it right. It's not yet ready for general consumption.
* tests/treestoretest.c: add a button and entry for the new
iter_change function
(iter_change): new function, to test
the row_changed signal implementation of the GtkTreeModelSort
* tests/testtreesort.c: cleanups, changes to test more features
of the GtkTreeModelSort at once
