Implement converter for video and audio blocks

[jxxcarlson]

Here is one of the lines that didn't render properly in epub3:

.Video: random walk
video::random2a.m4v[width=400, align=center]

This is from 01.ad in the processing-book repo. The video does render properly with asciidoctor 1.5. I used iBooks as the epub3 reader. Everything (text, images) looked OK with except the video.

That's probably because we never implemented the video handler for EPUB3 as it wasn't required at the time we were creating the backend...so you're not missing anything...just the converter is :)

I updated the issue title and added audio blocks since I know they aren't implemented either.

Thx!!

The new release is truly awesome. I love the level shifting.

I'm happy to report that Gitden now supports audio and video, so I finally have an e-book reader to test it on. We can do this now!

WRT video: Calibre only supports WEBM. Google Books claims to support WEBM + MP4 (H264). I would not be surprised if there are readers that only support MP4.

However, Asciidoctor video macro only allows to specify one file. We possibly need to do some trickery and look if there are files with different formats lying next to specified file and grab them also. I don't think we want to transcode on-the-fly during packaging.
