Add places pages

This commit builds off of @Skud's spike on locations and largely takes
off from the `nearby_members` feature which previously existed on
members.

One thing to note is that we needed to add a search route and action to
`PlacesController` to account for requests of new places as they could
not be redirected to properly from within `PlacesController#show`.
