Make cache manifest for issue #5 more relative.

I set the fallback entry for “index.html?” to be relative and this
fallback entry lets you test the app on a subdirectory of a domain as
long as you include “index.html”. In browsers I tested, there was no way
to make the fallback entry for “/?” relative, so that one has to remain
absolute and can only work on domain-level deployments.
