Some tweaks to improve alignment in table with checkbox

1) If a checkbox does not have a description (even if it is empty), layout will be broken as checkbox won't be aligned correctly

2) UPnP checkbox looks better with description instead of help

This commit fixes the two issues...

Whitespace cleanup

Make model_number customizable

Make presentation_url customizable

More icon and button consistency fixes. Ticket #5965

Fix formatting on the UPnP page, fixes #5970

Remove additional_files_needed entries

Set secure_mode=yes in miniupnpd config. Ticket #5627

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.
