Replace or remove "quad soon" message
The game includes a couple of default/builtin chat messages (both in the default “custom controls” area and in the quick chat menu (can be opened with one of the function keys)).
One of the default chat messages is “quad soon”. This doesn't make sense in Xonotic. There's no “quad” in Xonotic. I guess you meant strength. Right?
This ain't no Quake! Terminology should be used consistently in the game. Having multiple names for the same thing is confusing.
But ignoring terminology: I don't know if this chat message is even useful. If strength appears soon, everyone will see it highlighted in their HUD anyway.
I suggest to either replace the message (with “strength soon”) or remove it.
