Presentation-format recordings can take a long time to load in Chrome #1764

It looks like Chrome is downloading the entire video or audio file before it is 
able to start playback.

This appears to be because the webm file isn't correctly optimized for 
streaming - the 'cues' section isn't relocated to the start of the file.

The solution is to install the "mkclean" tool, and add it as a post-processing 
step to the webm media files. It performs streaming optimization for webm files.

I have a set of ubuntu packaging scripts for 'mkclean' ready, and the 
processing scripts change is trivial.

Primary wait is to get mkclean added to the build server so it can be used.
