Instead of adding stuff to `_shutdown()`, we can now register a shutdown
routine from the respective `init()` function of our modules.
This also has the advantage, that we're sure they're called in reverse
order from how the initialization happened.
I didn't simply use `atexit()` because POSIX says that the number of
possible callbacks is limited (min 32) and I was not sure whether
we will maybe extend this number at one point.

In the documentation of the `muc_nick` function we can read:
> The nickname is owned by the chat room and should not be modified or freed
We should reflect that in the return type and `strdup` the value for the
plugin API.

Use a singleton `Jid` inside the connection instead of always re-creating
a `Jid` from the same string.

Add ability to completely turn logs off,
Needed since `/logging` and `/history` didn't stop history logging
in the DB, only in files.
Command might break something on usage,
hence it was primarily introduced for privacy geeks.
