Missing some Tweak filter parameters

[Nero]

AVS+ adds new realcalc and dither_strength parameters.

Look: http://avisynth.nl/index.php/Tweak
Could you add them?
Another question: Is it possible to make manual changes to the avisynth script generated by hybrid? The one that is shown in "AvisynthScriptView".

I also found a typo that appears in the user logs when trying to use an opus audio in a format that is not raw/mkv/webm.

Error in audio job creation: Format opus is not allowed for mp4 output! Format opus is only allowed for raw/mkv/wemb output!

Says 'wemb' instead of 'webm'.
Nothing of extreme importance, but maybe you want to fix this.

Thanks!
