0.13.0 !!! The great compression!

So I got a VP9 plugin for my video editor, and with it reduced fill size by over 50%! The webm files had meta data for 4k (my resolutions) even thorough the frames were only 1080p. I went through and re compiled all the webm files with no 4k meta data.

Update contains

• Duck team, 55 renders and 11 webm animations
• Mallard team, 45 renders and 11 webm animations
• File size reduction from 7.29 GB to 2.97 GB

Sorry no Kuromorimine this update, It has been pushed back to 0.14.0 because of the great compression.
