More container and tree changes on all platforms regarding memory.
This should fix GTK3 memory leaks I wasn't previously aware of...
but it will cause all platforms to leak memory if strings returned
from dw_container_query_start(), dw_container_query_next() and
dw_tree_get_title() are not freed with dw_free() when using version 3.
