This is fix on Linux. Someone has to test it on BSD and fix IF there's
similar issue with the kevent based mechanism.

We need to mask and check if the intended events are received because
some events like IN_UNMOUNT, IN_Q_OVERFLOW or IN_IGNORED may arrive
without knowledge.

Added a user-script to send selected files using kde-connect.

The script uses kdeconnect-cli to send the files to the linked device.
Uses the .nnncp file to cat the selected files.
You can get system notifications using notify-send. This is disabled
by default.

`nlauncher` is POSIX compliant. It needs `fzy`.

NNN_SHOW_HIDDEN is removed.
