sfeed_{curses,frames,gopher,html,plain}: SFEED_NEW_MAX_SECS
By introducing the new environment variable $SFEED_NEW_MAX_SECS in all
sfeed_* utilities marking feeds as new based on comparing their age, it
is now possible to override this age limit.
This allows, for example, to be notified about new feeds within the last
hour with
SFEED_NEW_MAX_SECS=3600 sfeed_plain ~/.sfeed/feeds/*
while creating a beautiful web report for last week's news by
SFEED_NEW_MAX_SECS=604800 sfeed_html ~/.sfeed/feeds/*
