filesystem: Introduce the basic notion of 'logical channels'
cards can have multiple logical channels; each logical channel has its own state of what is the current selected file + application. Let's split the RuntimeState class into the global RuntimeState and the per-lchan-specific RuntimeLchan class. This code doesn't actually introduce any code that uses lchans other than the basic logical channel (0), but just modifies the data model to accomodate those in the future.
