Sync climbs

Logs into your Kilter Board account and pulls the latest climbs, grades and ratings for your gym down to this app. Your username and password are sent straight to Aurora/Kilter's own servers (kilterboardapp.com) by this server -- they are never stored, logged, or kept after this request finishes.

Heads up: Kilter has launched its own independent app and is moving accounts off this older Aurora-hosted backend, so this may fail or stop working entirely at some point. That's fine -- browsing climbs doesn't need this to work at all, since it runs entirely off the climb data already downloaded to this app. A broken/retired sync just means that data stops getting new climbs, not that the rest of the app breaks.
