Adds a module for Uldum to the RareShare Core addon.
NOTE: Not sure if there are different versions of the invasions, for now I chose to select based upon map ID 1527, but for some reason Uldum has 5 map IDs, one of which being 1575 (Meaning it was added later than the 1527 one). Not sure if this will make a difference in the long run, but if you run into any issues please let me know.
