Changed picture/pic link styling, added BE type

-Made the animal's picture on the View Animal page much larger.

-Changed the border on both the View and Pull animal pages to Gold.

-Used bootstrap button styling for the animal's picture switching buttons.

-Added styling to the BE Color, which shows the text in bold and the color of the behavior evaluation (Green, Orange, Purple).

-Added a small subscript "What is this?" button to explain what the colors mean. Currently goes nowhere.
Using wp_enqueue_scripts instead of echo

Switched to using wp_enqueue_scripts to include Javascript and CSS, instead of Echoing the Link/Script tags. Also included dependencies for jQuery for both view_animal.js and pull_animals.js, since they use it for an ajax query.
Fixed formatting bugs

Fixed a bug in view_animal.js where, if a field that needs to be formatted is not set, then the animal's detail rendering would skip everything afterwards.

Fixed a formatting bug in pull_animals.js where, if an animal had two large breed names, it would ruin the formatting of the animals below it. Now pull_animals only shows the Primary Breed, while view_animals still shows both.
Added Bootstrap CSS to enqueue_scripts_styles
