Make it so all the DB addons are marked to load by default, so the user does not need to go through an extra step when setting up. They can later turn off the loading of the other addons if they are trying to optimize startup time.

Internally we should make sure to wipe any data loaded for regions that are not the current region, since we would never need to actually reference it at run-time. This should hopefully reduce the memory usage after initial load, by getting rid of all non-current regions.
