Playing audio stream breaks due to progress bar

[hiviah]

This is similar to issue #30. If you try to play audio stream, it results in exception:

airstream http://ice1.somafm.com/groovesalad-128-aac -o appletv
loading can take a few seconds...
=> press [q] to exit airstream
Progress |=============================================================================================================================================================================================================================================| 100%

One workaround is to disable the progress bar like this, but it's rather quick&dirty fix:

thx for the input - I added a fix that should prevent error for invalid progressbar values.
