Several changes related to referring to remote URLs for sessions and files:
* Pull file dialog wrapper functions out from MainWindow into FileFinder
* If a file referred to in a session is not found at its expected location,
  try a few other alternatives (same location as the session file or same
  location as the last audio file) before asking the user to locate it
* Allow user to give a URL when locating an audio file, not just locate on
  the filesystem
* Make wave file models remember the "original" location (e.g. URL) of
  the audio file, not just the actual location from which the data was
  loaded (e.g. local copy of that URL) -- when saving a session, use the
  original location so as not to refer to a temporary file
* Clean up incompletely-downloaded local copies of files
