Rel19 Initial Dungeon Finder Commits

This will add two new files to the core that are necessary for the Dungeon Finder.

The Dungeon Finder is still a work in progress, however this patch will get rid of the annoying screen you currently see where the dungeon finder should be and will display almost everything that should be there in a "Blizzlike" manner
