14/A6/Sampler Demo mode; disable autosave

By keeping 14/A6/Sampler pressed while turning the device on, autosave is turned off. This mode is perfect for tweaking your song non-destructively, for example for passing your Woovebox to a curious friend, without having to worry about them destroying your songs.

Please note that a manual save option will become available in the context menu of Song mode's 'GLob' page (firmware 2421+).
