#87 auto link and duplicated names

[Benito van der Zander]

I have a type TX in unit A that is referenced in unit B as

//* Just a wrapper to unit A. 
type TX = unitA.TX;

If I write TX in the index document, it is auto linked to unitB.TX, when it should be autolinked to unit A.

If I write @noAutoLinkHere in unitB, TX in the index document is not autolinked anywhere, despite there still being the target in unitA.
