Add support for animations under IE

[Akeru]

I've created a branch with initial support for drawing animations under IE. I did not submit a PR because this is mostly a proof of concept. It works although it is lacking some feature (reverse drawing mainly). You might want to review https://github.com/Akeru/dmak/commit/9b99e40aaf6501a236052675095a4c004644db55 Note : jQuery is a had dependency for this to work.
