Make Examples Filterable in a More Meaningful Way

[sandersky]

An idea @gknoy and I came up with is to revamp the examples page to have filters that can be applied to find an example for whatever it is you are trying to do. For example we might present a multi-select filter for choosing a set of renderers that must be included in the example we desire. This would mean adding a bunch more information to the Ember Data models and Mirage mocks as well as updating the examples UI to present the filters. I'm sure we can come up with more meaningful filters beyond types of renderers as well.
