more button works

link at end now says `more...`

now keep track of the result offset in window.from. refactored
making a query request into query. keyup checks if search term
has changed and only calls query if it has. more also calls query
after adding 10 to window.from.

response handler only clears the result list if the offset is 0.

added query to url

url now added after hash;

added jquery-hashchange.js to detect hash changes; now detect hash
changes and, if hash is different from current query, set search
box to hash and trigger a keyup. whenever the search box changes,
set the hash.
