Add Guild Missions Overlay

[SamHurne]

Several users have made a request for a tool that allows them to see the path of bounty targets for Guild Missions.

Currently, the only idea I have for this is to show a small map of the current zone with the known path of bounty targets drawn. However, this doesn't seem like much of an improvement over just using the Web Browser feature to pull up a webpage with the same information.

Suggestions/ideas are welcome, and I will likely brainstorm a bit on this issue as ideas come to me.
