Extend fuzzyTime filter for dates older than one month.

Previously the fuzzyTime filter showed fuzzy value for dates no older than 30 days. After that it just displayed an unformatted new Date(date) which looks strange compared to the other displayed time strings.
Now it has been extended to show x. month ago and y years ago.

Fixes #799
