Your task in order to complete this Kata is to write a function which formats a duration, given as a number of seconds, in a human-friendly way.

The function must accept a non-negative integer. If it is zero, it just returns "now". Otherwise, the duration is expressed as a combination of years, days, hours, minutes and seconds.

It is much easier to understand with an example:

  format_duration(62)    # returns "1 minute and 2 seconds"
  format_duration(3662)  # returns "1 hour, 1 minute and 2 seconds"
