Add inline edit forms on index page, originally hidden, show with Edit link via coffee script. Spec still needs work.
Fix two examples, spec still does not test if update method is working, break update method to test spec.
Add .DS_Store files to .gitignore, re-enable ideas#update, add spec for updating an idea inline on index page.
Create edit_idea_via_ajax feature branch
AJAXify edit_idea form
