feat: allow admin to set default channel

A MeshChat administrator now has the ability to define the default
channel that a newly logged in user is placed into. This requires that
the administrator set the value `default_channel` in the configuration
file. Setting `default_channel` to an empty string ('') will continue
using the legacy setting of 'Everything'.
