Removed deprecated CreateWindowOptions

This replaces CreateWindowOptions `bounds`, `getBounds` and `setBounds` appropriately with `innerBounds` or `outerBounds`.
It also takes care of moving `width` and `height` set directly in CreateWindowOptions in a new `innerBounds` or `outerBounds` key.

See https://developer.chrome.com/apps/app_window for a full list of deprecated elements.

Note: the [Printing sample](https://github.com/beaufortfrancois/chrome-app-samples/tree/master/printing) needs more thoughts and will be committed in a separate PR.
