Split up post.php

[ryan]

post.php does too much. It serves the create and edit forms for posts and pages and dispatches actions for posts, pages, and comments. Let's break it up into multiple files.

• comment.php - Handle comment actions.
• page.php - Handle page actions and page edit form.
• post-new.php - New post form.
• post.php - Handle post actions and post edit form.

We might want to have post-edit.php and page-edit.php for handling the edit forms, but since this currently consists of simply including the forms from other files, it's not a big deal.
