MC Foo v0.0.7 released

* No longer use mpg321, python-hip is a python lib to decode mp3s. The turntable subprocess is gone, it's all in one process now.
* No longer use ao, it couldn't provide the non-blocking interface I want. Aiming for a pure-python solution, currently have to hardcode a few ioctl(2) values.
* For songs where the decoding library can provide timing information and seeking (oggs), the tap file now remembers the exact location in the song.
* "mc-foo addqueue" now takes multiple song names, priority is now an optional flag.
* Twisted API changes, reactors etc.
* Twisted packaging changes, now depend on python2.1-twisted.
* Some minor bugfixes.
