Prerelease v0.2.121

** After entering your password it will take a few minutes (maybe ten). It will appear to be doing nothing. If it fails, it should pop up with an error. Otherwise it should install all the dependences in the background and eventually pop up the GUI. If you do not want to type your password in, you can use the installer.sh script in the 'Terminal install or update' section of the readme. **

You can use the terminal version with "/Applications/Blu-ray to AVP.app/Contents/MacOS/Blu-ray to AVP". If you run the binary with any arguments, it will work like the previous terminal app. No arguments will open the GUI.
