Intermediate curriculum: adding discussion topics and hints around creating posts
Merge branch 'update_devise_instructions' of https://github.com/jessetoth/docs into jessetoth-update_devise_instructions
Remove use of hashrocket in 'Delete' link code

These days, the "Destroy" link for a scaffolded object defaults to using
new-style symbol syntax.

This also changes the link from
  confirm: 'Message'
to
  data: {confirm: 'Message'}
which is the way the scaffolds currently do it.

confirm: 'message' is deprecated in rails 4.
moving the line about HTML down underneath where views are discussed. I think this is where it was meant to be placed in the first place - it doesn't make much sense under models/topic.rb

Komodo edit page no longer has 'PowerPC' variant, instead linking
to Komodo Edit 8 (which is supposedly universal)

Removed highly useless "Diagnostics for Windows" page
Don't show 'Windows Colors' on TOC when linked from 'Configure Git'
   (you can now use the method link_without_toc to shadily provide
    a link without making an entry in the TOC)

Inline 'Intel or PowerPC?' page onto the 'Panther' page.
Fix typo.

The docs don't match the generated code.
Fix error output in tests.
