miniupnpd: Generate miniupnpd config using more explicit bools

The miniupnp config section has boolean flags that are either true with the value
'on', and are inferred to be false by omission or an empty value. To be more
explicit when generating the miniupnpd config, compare these values to 'on'...

Generate the UUID using the external interface MAC

Use the configured external interface to generate the UUID and serial for
miniupnpd.conf. Additionally, resort to using a random MAC on failure.

Parse package title, splitting into an array delineated by '/'.
So if the package title is "Services/Magic" the $pgtitle will be array("Services", "Magic") and the breadcrumb display will be as expected.

Wrap UPnP permissions processing in is_array(), the var may not exist especially on upgrade.
