Legacy Forever

A menu on the zone completion tracker, a new icon that matches the other WoW: Forever addons, and two fixes.

• Right-click a zone in the completion tracker for a menu: open the map or hide the section, as on the Legacy section. A left click still opens the map.
• Fixed the collapsed zone box on the world map keeping the width of the counts it hides.
• Fixed a "couldn't add a section to the objective tracker" warning after a slow login, when the section attached a moment later.
• A new icon in the addon list, drawn to match the other WoW: Forever addons, so it is easy to spot beside them.
