mod_auth_token: Timezone fix for TOTP checking luatz.time() returns milliseconds since epoch which is in UTC time, so we don't need to convert to UTC with gmtime. By calling gmtime, TOTP validation was failing when this module wasn't running on machine set to UTC time.

This module produces more detailed HTTP logs for Prosodys built-in HTTP
server. The format is similar to that of Apache and go into Prosodys
normal logs at the `info` level.
