Always transcode ALL streams

I just ran into an issue where only certain audio streams (which happened to be French) of a file got transcoded. -map 0 forces ffmpeg to always transcode all streams.
Added compiled Python bytecode to the ignore list
Added the post processing log to the ignore list

Added the post processing log from SABnzbd to the ignore list
Missing codecs no longer result in an error
Added the ability to choose a subtitle codec
Improved detection of empty configuration options
Merge pull request #106 from nightexcessive/master
