Searching is now implemented.

...except for unicode characters. I'm still not sure how we should handle those. Other than that, this should be everything we need for search. Right now the search icon is only present in the Home activity, but it's very easy to put that into other activities. The only other thing we might want is custom completion suggestions.

I ended up splitting the the database that held the full-text search stuff into two; one for events and one for teams. This allows us to sort them independently and group them in the search results. This does mean that the app will crash the first time you open it after installing this version. We really need a better way of handling database version changes...
