Don't fail assertion on 0-second meta-refresh

Browse Source 
In start_document_refresh, use register_bottom_half instead of
install_timer if the timeout is 0 because install_timer asserts that it is
given a delay greater than 0.

Add a test case, test/refresh-0timeout.html.  Note that
document.browse.minimum_refresh_time must be set to 0 to reproduce the
assertion failure.
