0.9.1 DrPong

11 years since previous xmms2 release. The diff accumulated 600 commits since last release.

So many things have changed outside xmms2!

This release catches up on a few things it ought to do a while ago:

• python2 was deprecated
• ffmpeg had about infinite amount of releases and API changes
• waf was refreshed
• hundreds of bugs were fixed
• and so many more things were improved

Please give it a try!
