NodeUp 53: Full review

* Fixed some proper name capitalization (github -> GitHub)
* Fixed some speaker names
* Corrected name drops and added links to some
* Corrected some hard to understand speech
* Trancripted missing speech between 1:06:00 and 1:07:00

In some cases I added and corrected some phrases that I thought were missing, but if at any point they were intentional we can revert.
