Subject: [PATCH] Create a label symlink to plugged device

Added a script in mount.d to create another symlink in
/var/run/usbmount based on the label of the plugged filesystem,
as provided by `e2label`.
Remove symlinks script modified to clean *all* existing symlinks
to unplugged filesystem.
Readme updated.
