Fix weird history problems.

Done by just listening for hashchange instead of popstate, and changing
location hash whenever we want to change the current page.

I've personally found history.pushstate/popstate extremely confusing to
debug, and something that works fine in one browser can cause infinite
loops in others, so I'd rather either use hashchange or a third-party
abstraction on top of pushstate that makes things easier.

combined two trivially nested 'if' statements
