component: Avoid adding to the global stream metatable

This allows component and client connections to be made side-by-side.
Previous to this change, loading this connection module would break the
ability to make client connections, due to overriding stream methods such as
:reopen() and :reset().

A next step would be to share the methods that the two connection modules have
in common.

local verse = require"verse";
local xmlns_receipts = "urn:xmpp:receipts";

function verse.plugins.receipts(stream)
	stream:add_plugin("disco");
	local function send_receipt(stanza)
		if stanza:get_child("request", xmlns_receipts) then
			stream:send(verse.reply(stanza)
				:tag("received", { xmlns = xmlns_receipts, id = stanza.attr.id }));
		end
	end

	stream:add_disco_feature(xmlns_receipts);
	stream:hook("message", send_receipt, 1000);
end
