0.11.0

A file that arrives after the call that accepted it stopped waiting is saved where it was accepted for, and the next receive_files reports it. send_file does not send this device's own PairOnce files or hidden files and folders. A part kept on disk continues in one process when two find it. A stale lock is cleared one process at a time; a finished file also moves to a folder on another disk. --ephemeral makes its home folder.
