Show most recent events first

[capjamesg]

A query such as "homebrew website club meetings" or "website club event" should show recent events at the top of search results. There are a few ways this could be implemented:

1. Add a weight to recent events in the search rankings. Thus, more recent events would show up higher in search results. This weight would no longer work when the event had passed.
2. Add a new widget that shows events. This would involve an additional API call in Elasticsearch so performance must be considered for this course of action.

I am leaning toward implementing the second idea at the moment. However, the first implementation may be good to look at if there is a need to optimize for other date-sensitive queries. I have not done enough research on date-sensitive queries on the search engine to make a firm recommendation on whether such logic is even needed yet.
