v0.7

This release makes it possible to have a video call with Kvazzup without having to open firewalls or know the other person IP address. Sadly the authentication has not yet been implemented so wider usage is not yet possible. This release also improves the audio processing, especially with regards to echo cancellation using Speex Acoustic Echo Cancellation (AEC). One final improvement is the adoption of uvgRTP for a more reliable and performant Real-Time Transport Protocol (RTP).
