Pull coreos changes into this fork
Swapped the clients with the features on the clients matrix so it is more comprehensible. The old version got too large to show on the screen. This new layout added a language column so you can quickly see the language of the client library.

Added alphabetical sorting to the clients list.

Also moved v1-only clients to the bottom since v2 is what most people are looking for today.
