Change order of deployment

[scottgonzalez]

The wordpress-sync task currently runs wordpress-sync-terms, then wordpress-sync-posts, then wordpress-sync-resources. This means that a post can be updated and link to a resource that hasn't been published yet. To prevent this problems, the sync tasks should be split. I think the right order is:

1. Add/edit terms
2. Add/edit resources
3. Add/edit posts
4. Remove posts
5. Remove resources
6. Remove terms

Removing terms at the end also allows posts to use keywords that aren't defined up front. See

grunt-wordpress/tasks/wordpress/taxonomies.js

Line 272 in f368a4a

// TODO: Don't delete terms until after processing posts.
