Mood is no longer supported

[b1llab0ng]

When submitting presence/setpresence, Hangout server returns an error that the Mood feature is no longer supported.
I removed the mood parameter from the body header. Hangupsjs still works and stopped retunring the Mood error message.
I did a dirty patch to test that I could get rid of this error message by simply removing the line #367 from client.coffee (v1.4.0-beta), and it worked.
For a clean job, would need to remove mood references throughout the code.
