app: add gimp_container_search()
Add a new GimpContainer::search() virtual function, and a
corresponding gimp_container_search() function, which works
similarly to gimp_container_foreach(), except that the callback
returns a boolean. When the callback returns TRUE, the search is
stopped, and the current object is returned.
Implement GimpContainer::search() in GimpList.
