add fix for hiding Plain Eggs on mounts page
add padding-top: -30px  -->  vertical-align: top  fix from a previous PR
remove unused menu.mounts style (probably best anyway to keep using menu.pets in both pets and mounts pages for consistency of appearance)
make whitespace consistent (tabs changed to spaces) - yes this IS pedantic, sorry :)
fix bug where dropEggs were used for both types of mounts (instead of 'source')
fix bug where quest Pets were being used instead of quest Mounts
