1) Ran all plugins through javascript formatter to make them look nicer/ have correct javascript formatting.
2) Added comments to all plugins.
3) Modified all plugins that have checks for inputs to check for existance of inputs itself.
4) Modify 5ConvertAudio so that you can just put "true" in a single input, rather then having to put false in the opposing one. If only 1 action is wanted.
5) Fix for 3CleanAudio & 4CleanSubs where if language meta was completely missing then plugins would not set it to the specified tag language.
6) Correct 4CleanSubs input title of "tag_title" to "tag_language"
