added fade-in animations :D, updated moot to new version, fixed footer being too long on mobile

FadeIn animations can be added to any HTML element using the
`animation` and `-webkit-animation` CSS attributes.  Sample:
animation:fadeIn ease-in 1;
animation-fill-mode:forwards;
animation-duration:1s;
animation-delay: 2s;
-webkit-animation:fadeIn ease-in 1;
-webkit-animation-fill-mode:forwards;
-webkit-animation-duration:1s;
-webkit-animation-delay: 2s;
