- Removed Self-Links and instead used another way of making custom id's
- Removed TOC
- Removed Back to top arrows
- Made FAQ an extra page

This allows for quick review of last build.

- properly categorize all patterns
- remove pattern list from readme
- minor fixes to readme
- removed "introduction" because its not a pattern and an error i
committed some time ago

Agreed guideline is conveyed and configuration link for eclipse and IntelliJ is also added.

I did the job and splitted up the readme, hopefully everything was
splitted correctly...

Links to various important sections of README is provided at the top so that it becomes easily navigable.

Also reworded some sentences and wrapped one or two huge lines I would need to
change anyway.

Closes #192

Notes:
  some lines had breaks at varying positions, fixed to 80.
  this improves readability to me immensely
  some stuff should not be wrapped and other parts are just hard to
    wrap, so I am satisfied with this for now.
