Advanced Filters - Dungeon sets filter

This is a plugin for the "Advanced Filters - Updated" addon.

Dependencies:
Advanced Filters - Updated and LibSets

Features:

• Show only items that belong to a particular dungeon set
• Show only items that belong to any dungeon set

Use command "/af_dungeonset" to toggle between showing only "All dungeon sets" entry or one for each set.

Base code was taken 100% from Baertram's Monster sets filter plugin and I changed the names to "Dungeon" + made it read the dungeon sets instead!
