Refactor wikipedia entries to be stored as events and remove table #46
Description
We don't want a whole table for a feature that is not first class. We want to remove the wikipedia model and instead use the events model to store the JSON for individual wikipedia entries. This way it can be used in event memory easily. If eventtype is wikipedia, main event data is the wikipedia response json, and we use one of the other fields to key the name of the wikipedia article so it's easy to find later... something like that...
