Nothing really to see here -- this only relates to my build/test
environment.
Ignore hidden (.xxx) directories

Don't monitor any directories beginning with a dot (ie hidden
directories). I'd never noticed this before, but since moving my media
to git-annex I now have a '.git' directory that I obviously don't want
to monitor.
Also trigger rescan if an attribute changes

This will help in the scenario where you copy music to the share but its
default permissions/ownership prevent Squeezebox Server from scanning
the files when the scan is triggered.

Now, when you've fixed the permissions on the files this re-triggers
another scan when the files will now be readable and they'll be found by
the server.
Merge 'feature/attribute-changes' to develop

Fix to not picking up new music if attributes prevented the scan from
finding it -- fixing the permissions will now cause a re-scan and these
files should now be picked up.

Hidden directories (beginning with a dot) are now also ignored and are
not monitored for changes.
