Generate missing Nginx mime types using /usr/share/mime/globs
Nginx comes with a rather small set of mime types compared to a default Linux system
Linux uses a glob pattern to match a filename while Nginx matches only extension, but we can still use every glob in the format of *.ext
So here is a small PHP script converting/sorting/filtering/formatting everything in a nice output.
