mumctl status: sort users consistently with Mumble

[Lykos153]

Hi! First of all: Thank you for this great peace of software! It's helping me a lot in my endeavor to make my system completely keyboard-only. Now to my feature request:

I have some meetings where the speaker order is determined by the order that is shown by Mumble which I think is alphabetical. mumctl status seems to use a different order, however. Currently I'm working around this with watch "mumctl status | tail -n+4 | sort", but it'd be nice if the sorting was consistent with Mumble already.
