gfycat mp4 support.

[mac1202]

Hi, in the mime_parsers.py you choose webm as default format for gfycat, but gfycat provide better and smaller file in mp4 format. For example here the output of youtube-dl --list-format on a gfycat link

webm         webm       1920x1080  56.50MiB
mp4          mp4        1920x1080  4.77MiB (best)

By modifying the mime_parsers.py I get the mp4 as default format, here's the modifications
