Title: Updating webp formula to latest stable release and adding webp-mux to it.

The team behind webp told us that we should be using webp 0.3.1. This pull request includes the updated file as well as the sha1.

We also included the mux, demux and encoder flags that generate some additional headers in the machine that allow for improved usage of webp.
