Wrong/Missing links for Klaus Iglberger's Breaking Dependencies series

[JamesHuang-TW]

The README.md contains a broken link to "Breaking Dependencies - Type Erasure - The Implementation Details". It links to the missing Item of Iglberger's another talk: Breaking Dependencies
The Visitor Design Pattern.
