Just a small update here, but a good one!

We've fixed the "addon.conf" bug that was incompatible with certain maps and gametypes. So now, instead of voting a map and nothing happening, it works!
(Thx to AnthonyJ for the hint)

And while we were in there messing around, we decided to add a nice feature: You can now view the server's maplist instead of your own in the vote menu.
