Duplicate definition warnings when using contiguous IDL

[inexorabletash]

example:

<pre class="idl">
interface Foo {
  attribute DOMString attr;
};
</pre>
<p>The <dfn data-lt="Foo.attr">attr</dfn> attribute's getter must...</p>

Yields: ERROR: Duplicate definition of 'foo/attr'

Note that the id/href do end up being created correctly (in this case, id="dom-foo-attr").

@inexorabletash, try the following:

<p link-for="Foo">The <dfn data-lt="Foo.attr">attr</dfn> attribute's getter must...</p>

Should hopefully work. There is some good guidance here that should hopefully fix all the issues in the IDBlv2 spec (which I was not fully aware of):

(please reopen if still busted or other issues/questions come up)

After the fixes were made to #470 this became a non-issue. The IDB spec is good now. :)
