Inserts a new key and value into a GTree similar to g_tree_insert().
The difference is that if the key already exists in the GTree, it gets
replaced by the new key. If you supplied a value_destroy_func when
creating the GTree, the old value is freed using that function. If you
supplied a key_destroy_func when creating the GTree, the old key is
freed using that function.
The tree is automatically 'balanced' as new key/value pairs are added,
so that the distance from the root to every leaf is as small as possible.
