Removed old page
Search loading progress, delayed instant search

Reverted http() to the one from Freetron since I want the progress
function. The only difference is the GET instead of POST. Also, don't
clear the loading message on query input until after it's loaded.

Search as you type, but after a slight delay so that it'll run the
search after you pause in typing. Previously, it would slow down for
each letter you type because searching takes some time.
