iso 8601 date format in top_status_line

Hi John, hi slrn users,

I am using the C locale for LC_TIME. Though, as I am not used to the
resulting date format in the top_status_line of slrn, I would like to
propose the possibility to use the iso 8601 date format as an option.

If there is demand for user defined date formats for the
top_status_line, I could introduce a top_status_date_format variable.

As for me, the iso 8601 date format as an alternative is sufficient.
