Settings: Change 'Model Number' to 'Model Name'

Most devices have the Model Number set to something like 'One' rather
than 'PN072', therefore they are using the Model Name not the Model
Number. Therefore, either every device should update to properly refer
to the Model Number, or we should update Settings to correctly state
that it is the Model Name.
