// AddRequestHandler adds a request handler to this client.
// A request handler *must* be a function taking a single argument, and that
// argument *must* be a pointer to a recognized 'ecsacs' struct.
// E.g. if you desired to handle messages from acs of type 'FooMessage', you
// would pass the following handler in:
//     func(message *ecsacs.FooMessage)
// This function will panic if the passed in function does not have one pointer
// argument or the argument is not a recognized type.
// Additionally, the request handler will block processing of further messages
// on this connection so it's important that it return quickly.
