I have created forward and rewind buttons to draw on the info bar. In
addition, I have created seek_sec() to seek the song by X seconds.
Right now, the seek buttons add +/- 5 seconds to the current position.
I can now change the volume using a button in the gui. Additionally,
the volume is stored between sessions, and the correct value is loaded
when libsaria is initialized.
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.
