Made a sharp delineation between required and optional study topics.

Moved these down to the optional area:
- endianness
- garbage collection
- unicode
- emacs & vim
- unix command line tools
- design patterns

Removed a video and link from prerequisite knowledge that were overly complicated for the topic.
