Add API for removing nodes from arrays and objects

Write and document json_object_remove_member() and json_array_remove_element()
which can be used to remove a JsonNode from a JsonObject or a JsonArray
respectively. This way, the JsonObject and JsonArray are API-complete and
the object model can be manipulated in code.
