Add support for cross-domain AJAX requests to REST console.

Enables RemoteConsole to add the appropriate HTTP header when responding to requests that use Cross-Origin Resource Sharing (CORS with simple requests). The allowed origin is set with configuration option "ConsoleAllowedOrigin" in section [Network]. For a suggestion to make this configuration option more flexible, see the TODO comment in the source code.

The WifiConsole uses this functionality with grid mode.
