 Subject: [PATCH] Limit Custom Map Rendering
 
 The default CraftBukkit render sequence for maps is ridiculously slow. By only using it when a custom renderer has been added (rarely in most cases), we can fallback to the Vanilla renderer for general usage. This leads to a much higher effiency overall, especially if no plugins are rendering such maps.
