This reverts commit d678fa56d127b93cfa10ccc53af81a6f3c9fa830. The
reference counter, flawed as it is, was masking far more issues than I
realized. It would require a more significant rearchitecture of the
code to remove it. Probably better to keep it and try to improve it for
now.
This was an old attempt at gracefully unloading channels that still had
pending callbacks. Its implementation was always flawed, and the number
of places where it was used is small enough to replace with
straightforward checks for whether the channel has been unloaded after
an asynchronous operation. Hopefully fixes the stuck 0 user channels
issue.
We now allow server operators to customize the /r/ part of the channel links
The new config option in the template is commented and the config module validates and will terminate with status 78 if an improper value is used.
We've also dropped some old cruft and uses a more elegant method to assign CHANNEL.name
Resolves#668
The `from` field has existed for ages, but was never actually displayed.
Displaying it to users reduces confusion about who is making the
announcement.
