Added growing animation

Added a growing CSS3 animation to the animal's pictures when they are hovered over.
Made animal name page title dynamic

Made the animal's name page title change dynamic, so that it takes the current title of the page instead of a static "View Animal | Sacramento SPCA". This allows for other sites using the plugin to have their own title instead of the Sacramento SPCA's.

Also cleaned up comment indentation, and some function indentation.
Moved fields and BE desc. to json file

Moved the animal's detail field configuration, as well as the Behavior Evaluation color descriptions into a JSON file. This makes it easier to change for end users, as well as keeping backups when an updated version comes out.
Edited readme

Updated the readme with information about the new config.json file
