Adding onto #97, it is currently very difficult to find a very specific entity in your game. Sorts mediate this, however fundamentally there needs to be better capabilities to search for them.

I have already laid out the ground work for the search filter's functionality. Not the best implementation yet but it works reasonably well without being intrusive for anyone to call. The function searchFilter can be found in the branch "search-filter". You pass in a world and a query string. E.g. searchFilter(world, "Test, Friend, !Hello, !Goodbye") which will query for entities with Test and Friend while skipping any entities that contain either of Hello or Goodbye

The idea for the implementation would be to grab the input of a textbox and feed that to the searchFilter's params. And then taking the returned entities and display them on the widget.
