Subject: [PATCH] Use channel default auto archive duration

Currently creating a new thread uses a default auto archive duration of
1440 minutes, or 1 day.

Rather than prescribing our own default, we can use the default auto
archive duration that is set on the channel. This ensures that newly
created threads will respect the default auto archive duration as
prescribed by the user.
