EPDiy upgraded to latest version + video experimentation

Please note that parallel driver epdiy is not anymore a requirement and after last update epdiy V6 is not part of this repository, only linked as a git submodule. So in case you want to use our experimental implementation in C++, please pull the git submodules:

git submodule update --init --recursive

In this version we packed up a few new experiments related to animation and video that you can find in the main/www-image directory.

This is not exactly video, since even with EPDiy parallel driver the framerate is too slow to call it video, but it might work for small epapers that refresh fast where you want to show simple animations.
