* NEED SOURCE: the track needs source files and won't be considered until source is presented
* NEXT POLL: the track will appear in the next poll (a track stays in this state if a poll result was inconclusive)
* REJECTED: track was decided to not to be used in Xonotic for now. However, a new map using that track, especially if it works very well with it, can possibly bring the track "back to life".
