[Nitro] og: automatic deletion of records in M:N relations?

[Riku Räisänen]

Try to set the relation only to other of the classes (it's two-way 
automatically).

Also, try this:

class Item
    # ...
    joins_many Tag
    # ...
end

class Tag
    # ...
    belongs_to Item
    # ...
end

so Tags get deleted if the Item is deleted, I don't know why you would 
want to remove the Items if a Tag is removed...

can't test these out, in a hurry.
