Adding note about using "--demos-binary" option to specify the filepath of the demos binary as an alternative to making sure the demos binary is in the PATH.
Fixed a typo "can'tbe" -> "can't be"
* Where available - on Win8+ basically. On win7 the video doesn't play (but most
of the demo also doesn't work, so that's not much change).
* Added a short 10kb clip from Caminandes (http://www.caminandes.com/sharing)
* Built entirely independently of the main renderdoc build (for now).
* Contains python scripts & framework for running tests on a renderdoc build,
which will be run nightly.
