Removes a key/value pair from a GTree.
If the GTree was created using g_tree_new_full(), the key and value
are freed using the supplied destroy functions, otherwise you have to
make sure that any dynamically allocated values are freed yourself.
If the key does not exist in the GTree, the function does nothing.
