A few small fixes along with some major refactoring in preparation for sharing a large portion of our codebase with the upcoming mobile app.
- The call back button on the voicemail page has been fixed
- It was possible to break volume control on calls, although unlikely. It is no longer possible.
- The icon next to a contact in the contact list was sometimes incorrect in regards to chat upon adding a contact, but now it will be updated correctly.
- Video no longer appears cut off for non-square dimensions (mobile video, for instance).
- Update SIP.js to 0.10.0.
