Removing hookref-old.md
Created by: mickadoo
- Remove
hookref-old.md
and move relevant content to other pages - Add section on dealing with custom fields to civix page (I'm open to relocating if there's somewhere better)
- Updated some links to the wiki / broken links to blog posts
- Removed warning about user_save for Drupal since I couldn't find any information on the
inCiviCRM
config variable - Added Wordpress hooks section
