First cut at cleaning up Sergio's example code and moving some common code to SkWindow.

Eventually, this will be moved to be a peer of SampleApp so it is compiled by the bots to avoid future bit rot.

Also ignore XCode auto-generated flag in CommandLineFlags, and remove the unused multiple-example part.
