Ported the components i need for a basic stream

The porting was not much [092db60]
I almost have everything i need for a basic pipeline consisting of the following:

• Audio test and video test producers
• Audio and video encoders (Vorbis and Theora)
• Muxer (Ogg)
• Consumer (http streamer)

I have some issues when testing httpstreamer.py:

Ran 2 tests in 0.012s

TO DO:
*Get successes on the test for the http streamer
*Try to figure out why test_common_gstreamer returns 2 fails on the Caps test
*Get in contact with someone from Twisted and ask for reactors compatible with gi
