So I tried adding associations to node/way/relation along these lines:

```ruby
has_many :element_tags, :class_name => "NodeTag"
```

and with all three in place I could then do:

```ruby
Relation.preload(:relation_tags, :relation_members => { :member => :element_tags }).find(2)
```

and it would preload everything.

So as I suspected we just need to rename the associations to have a common name and it should all work.

Note that the old models already have a common name (`old_tags`) so this should already work there.
