Small Error Fix

Fix for Duplicated Uppsala issue
Added Ottarshogen

MB+ Localization Updates

Update:
Updates to Medieval Arts (7 new buildings with graphics)

I also added a debug decision that will "TRY" to add these updates to an existing game. It may not work but it's worth it to try. To do this, load the game in debug mod, load your game, run the Update Special World decision. save it, exit game, then play as normal.
