Fix for bug 66058: dates in Created and Changed date columns in buglists are now in context with how old the bug is.

within the last 18 hours: time only (12:24:34)
within the last   6 days: weekday and time (Fri 12:24)
within the last 100 days: month and day (01-19)
older than 100 days: previous behaviour (2001-01-19)
