Fixes on HTML and CSS Customization

 Now accepts either class or tag or both for styling elements (such as date, author, etc. to display). When just using a tag, it will sorround the element with that tag. When using just a class, it will wrap the element between span tags and the given CSS class.

Fixes bug on `post_status`
