Replace old JavaScript with simpler vanilla version

Pomf's old JavaScript is a frozen dependency hell with an old version of
Zepto. The amount of code included has reached the point of
unmaintainability, where nobody really understands very well how the
code works.

This code gets rid of all the previous client-side JavaScript and
replaces it with new, vanilla JavaScript. No dependencies required. This
new JavaScript should be quite a bit faster too.

Browser backwards compatibility has not been tested yet, however it is
expected that IE10 and later will work, improving our current backwards
compatibility.
