Models, some client ui's, some func. def.s changed
Changes list:

- Models updated.(Check server/models/models.js)
- Phone database tables have changed.(Check openDatabaseConnection()
	function of the client)
- Now, replies are sent with the forward count of the request; so, we
	can keep track of how many times the request is forwarded before the
	reply.
- Request page ui is now compatible with the spec.
- Response page ui is now compatible with the spec.
- Server is compatible with the new client updates.

NOTE: More testing may be needed.(With at least two devices if possible.)
