[jitsi-dev] Unstable branch

I had some changes that I wanted to commit (so I can refer to a commit
in the videobridge repo) but didn't want in master before we release the
new minor, so I made the 'merge-me-after-the-bugfix-release' branch.
Feel free to push similar stuff.

Speaking of a release, there were few reports that audio/video on Windows is still broken in the nightlies. I haven't been able to reproduce those. Anyone else?
