Fix for #17.
Fixes flake8 and isort issues.

Newer versions of flake8 are stricter about some whitespace things, and
picked up a new error in existing code.

This class was removed in Wagtail 1.8, replaced by a few utility
functions.

Switched the ordering of transcodes so transcodes are preferred. Made the regular template tag use the method from the model

Fix for #7

Added quality field to transcode form. Created method of transcoding using different qualities for each media format

Allow users to change the thumbnail. Use the thumbnail as the poster for the video. Also fixed bug with transcoding form always passing no data

Got rid of extra option for ffprobe, also added new logging for errors and changed video duration to a duration field
