Auto-free inactive help channels

[Zabuzard]

Overview

A help channel that has no activity for 2+ hours should automatically be marked free (as if using /free) by the system.

A small explanation message should also be posted, i.e. as if using /free. But maybe with some minor adjusted text like "was automatically marked free because ..." to explain the situation.

Alternative

Wait until we change our help system completely (thread/form based). But that might still take a couple of months and it would be nice to benefit from this low hanging fruit today already.

How should that be implemented? a routine?

How should that be implemented? a routine?

Yes. A routine that is triggered maybe all 5 minutes, checks all busy help channels for their last message timestamp. If greater 2h, free it. Something like that, I guess.

the code is already written, its currently set to an hr but the values are static constants in the config class so its simple to change

the code already checks channel status on boot, that same method just needs to be called by the routine FreeCommand#checkBusyStatusAllChannels(jda)

it already puts the same "channel is available message" as using /free would and it already correctly sets the channel status.

its probably 7 lines of code to add
