Fix s2s once and for all - Moved dialback to the new mod_dialback (mostly). - Modules can now supply a list of origins to handle to add_handler - Modules can now handle and process any stanza, overriding the core - Modules handle non-jabber:client/jabber:server xmlns'd stanzas

local t_insert = table.insert;
function import(module, ...)
	local m = package.loaded[module] or require(module);
	if type(m) == "table" and ... then
		local ret = {};
		for _, f in ipairs{...} do
			t_insert(ret, m[f]);
		end
		return unpack(ret);
	end
	return m;
end
