Fix image CSS class, adjust search

Forgot a search update from a while ago. Also added a fix for the image CSS class-- it can be tripped up if we're using an ImageBackground Atom (which extends Image), because for some reason there are 2 of the same CSS class name coming in. Rather than figure out what's causing that, I used array_unique before we convert the CSS classes to a string to filter out duplicates.

Initial release

Figured it was about time to just go with v1.0, since we're about to phase this thing out anyway.

Includes fix

v0.18.0

Forgot to update the includes file

Added new BackgroundVideo, BackgroundVideoVide, ImageBackground, PostParentLink atoms

Add Atom Class Shorthand, Post Loop Properties

AtomTemplate needed a class shorthand, so that classes from Sections from ACF Flex Layouts could get in there.

The loop_posts method in OrganismTemplate got beefed up: it now supports passing in different a post structure based on the post index, and adding markup before/after specific posts. Some examples would be:

• $this->post_0_structure
• $this->post_3_structure
• $this->post_last_structure
• $this->post_odd_structure
• $this->post_even_before
• $this->post_4_after
• $this->post_last_after

There's also a filter for individual post structure, in case you need to test against something else, like a meta field.

"Loop" atom if check fix

Was checking against $data instead of $this.

Minor bugfixes

Better check for attachment ID in the Image, post in the Post Author Link, and a check in Taxonomy List in case there are no terms.
