Never go full yolo

Checked the code 1337 times and didn't find bugs.
We can use travis to continuously verify that everything is fine,
so using the UnsafeBitstream for Release builds should be no problem.
Also: OMFG PERFORMANCE
Added Bitstream-Debugging

Just so we're _really_ safe and stuff like #15 can be detected earlier.
Restructured travis.yml commands

Also, added cleanup to detect timeouts
