util.set: Change tostring format to {a, b, c} Makes it easier to make out where the set starts and ends in cases where it may get embedded and tostring()-ed in a log message. { } taken over from util.array for consistency with some other systems syntax for Sets, e.g. Python

module:log("error", "mod_pep_plus has been renamed to mod_pep, please update your config file. Auto-loading mod_pep...");
module:depends("pep");
