TrackThat

• Fixed some issues related to changing to subzones (ex: caves, ...)
• Added support to track nearby Challenges locations. It works in Housing too for plug challenges, just no indicator arrow because it is no available. Range is set to 250m. I can do full zone, but I found that it crowded the list a bit too much. I might add a setting to disable that limit later on so that you could switch it on/off when looking for a specific Challenge in a zone.

Known issues:

• When going into caves and such, the tracking of Challenges becomes a bit wonky, from what I can see there is not much I can do about that because of the way the API provides data
• Some targets are tracked without being part of an active quest. I need to figure out why.
