Added Puppy Room to pullanimals.php

Added the Puppy Room as a valid area for dogs to be pulled from.

Fixed a minor spelling mistake

Added the basis for sorting the results (Currently commented out, as I am working on data cleanup before the JSON is transmitted)
Added function to clean up pullanimals data

Added a function to check if an animal's data is missing, and removes the entry if it is. This removes the multiple empty arrays that appear at the end of data responses.
Added sort function for animal names

Added a sort function to sort the animal results by their names.
Created render_animals_html function

Created a function to encapsulate the mapping and creation of the all of the individual animal nodes
Added sort buttons

Added sort button function, which creates the sort buttons and gives them a click event handler which sorts the results and re-displays them. Currently supports sort by age, sort by breed, and sort by name. Will add Sort by BE color in the future
Converted sort buttons over to function

Converted all sort buttons over to the create_sort_button function.
Fixed bug with sort buttons

Fixed a bug where using the sort buttons caused the tooltip regarding animal BE colors to be not function.
Added toggling ascending/descending to buttons

Added a toggling ascending/descending status which determines the order in which the animal results are display (they are sorted either way, but reverse when the button is in descending mode.)
Styled sorting buttons, code cleanup, misc changes

Added Bootstrap styling to sort buttons. Also turned (asc) and (dsc) into up and down arrows.

Added comments, aligned some code that occured over multiple lines

Changed the View Animal page to display age as "# year(s) # month(s)" instead of "#y #m"
