Improvements to scheme handling (issue #246).

- Break CefRegisterScheme into separate CefRegisterCustomScheme and CefRegisterSchemeHandlerFactory functions.
- Allow registration of handlers for built-in schemes.
- Supply scheme and request information to CefSchemeHandlerFactory::Create.
- Add CrossOriginWhitelist functions for bypassing the same-origin policy with both built-in and custom standard schemes.
