Adds animations to the pipboy, repalces builder PDAs

-UPDATED 8/24/2011- Now works with the Dues Ex promotional item, update. These animations replace the PDA's and work 24/7. regardless of what you have equipped. Please note that the destroy pda draw animation doesnt always play. This is a bug that also occurs with the default animations. There is nothing i can do to fix it. please accept my apologies and forward all animation bug related complaints to valve.
