[FEATURE] Autokick of ghost characters

[Jomshir98]

Adds ability to configure automatic kick of offline characters.
The scan for offline characters happens regularly by Shard and checks if character has been offline for X minutes before requesting Directory to kick it. If the request fails for whatever reason, it will be re-attempted during the next cycle.
Also has an option to ignore Owners/Admins/VIPs of a space.

Additionally increased the randomness of initial position generation 5-fold.

I tested it a bit more and I have three improvement proposals to make this more usable:

1. It currently also kicks ghost in room devices. This is may be undesired sometimes and also leads to the need for another manual step due to the issue that I described in Clear kicked/banned players from device slots automatically #714

I propose to add another toggle "Also affect characters in the slots of room-level items" with a default off.

2. I think public and private spaces are a bit different, so another toggle "Also in effect when the space is private" with a default off.

3. Less of a priority, but nice to have: When you currently enter a value of "0", I would expect that it kicks instantly when the disconnect message is printed in the chat (ideally without a separate chat message to not be spammy). Currently, a value of "0" still means after 1 minute. This is very minor and likely too much effort to address right now, but I thought it may be a nice idea. (or we simply do not allow to enter any values below 1)
