special brand field for the club=scout preset

[tiptoptom]

On the discussion page at wiki, it was proposed to enter the Scout organization in brand=* .

But the field name "Brand" could be confusing in the Scout context. Therefore, I would suggest to create a second field for brand=* using the name "organization" and to use it in this case.
