failover: transfer of channel / category

[sudojunior]

If either of the channel options are changed... (posts channel, category container)

• Determine if clean up is necessary.
• Determine if permissions for clean up are available.
• ... do it

Clean up of posts channel means removal of all game posts - and likely reposting them into the new channel.

Clean up of category container means transfer of all channels matching the category id into the new category - much easier than removing and recreating them.

Closing, new rate limit of 500 channels per server per day severely hinders the intended logic to transfer channels from one category to another. Literal transfer would be up to the server owner to handle, but still not preferred given how it would behave if permissions are synchronized for another category (weak point - external intervention / interference).
