Make ngx_pagespeed behave like mod_pagespeed with regard to Flushing (#1217)

Browse Source 
This change makes ngx_pagespeed listen to the FollowFlushes option.
When set to on (=default), ngx_pagespeed will forward incoming flushes
to ProxyFetch. When writing output, we'll now also set the flush flag on
the buffers we are about to send downstream.
