error message to channel should suggest restarting

https://github.com/lykoss/lykos/blob/4cf81714262b4190104b8db669c7504b48f166f3/messages/en.json#L1379 This could say something like: "An error has occurred and has been logged. If errors persist, try restarting the bot." Not every repeated error is a sign of a corrupted internal state that needs a restart to fix, but most of the ones I see on the official bot at least are either that or a direct response to a particular thing happening (like a broken !command). Experienced bot admins know how to deal with that but new ones don't always.
