iterate on previous commit which adds $SFEED_NEW_MAX_SECS

Separate the common pattern to get the time to compare new items in format
tools to the new util function: getcomparetime().

Some changes and notes:
- Change it so it is OK to set this value to 0 or negative (in the future).
- sfeed_curses: truncating newmaxsecs to an int would limit the value too much.
- Just use strtotime() and parse the value to time_t. This is a signed long
  (32-bit, until 2038) or signed long long (64-bit) on most platforms.
- sfeed_curses gets the comparison time on reload aswell and it needs errno =
  0, because it uses die(). time() is not guaranteed to set an errno if it fails.
- Rename environment variable to $SFEED_NEW_AGE.
