Add a standby mode screen, this is a significantly cutdown version of…
… mythwelcome, accessed directly from the frontend so by design doesn't duplicate any information or actions which can be accessed elsewhere in the frontend. Standby mode is currently accessed from the Main Menu context menu and the option to make it the default exit action will follow. When in 'standby mode' the backend will be allowed to shut down and when that happens, optionally the frontend may be shut down as well. You may continue to use mythwelcome as before if this new mode doesn't suit. The initial default theme is very basic, I hope to add some icons to the status statetype before the 0.25 release.
