I have reworked the gstreamer functions from Ocarina 4.0 and combined
everything into one file. I have also created an audio test that plays
a song from my library.
I combined various parts of the Ocarina 4.0 event system into one file.
The new event file has threading abilities built in, so I no longer need
an external file for that
I revised the Ocarina 4.0 map class so it will hopefully have better
performance. I also began working on a new testing system so testing
specific changes should be easier than with Ocarina 4.0
