Add a DX11 video plugin.

Might or might not work for you, yet.
Anyway, read the soon to be created forum thread on this plugin before asking any questions.

Huge thanks to rodolfoosvaldobogado for helping me out in various areas.
Also, thanks to everyone on IRC who supported me during development ;)
