- Typing a directory into the input control of the `FileOpen` dialog now
changes the directory in the navigator and stays within the dialog.
- Sprinkled some `PermissionError`-handling code around the `FileOpen`
dialog, so that if the user tries to go where they don't belong, the
application won't blow up.
- Made it easier for the user of the library to restyle the look of the
`FileOpen` dialog (documentation will follow for that at some point, but
reading of the `DEFAULT_CSS` will give some ideas).
- Simplified the internals of prompt creation in the `DirectoryNaviation`
widget, with a view to setting about improving what's shown and adding
configurable styling pretty soon.
