More flexibility

Please could you change the options for timelimit:

1. So it is translateable
2. Longer times

In my copy I have changed user_alert.admin.inc from line 28 to this:
'#options' => array(
0 => t('Never'),
900 => '15 '.t('minutes'),
1800 => '30 '.t('minutes'),
2700 => '45 '.t('minutes'),
3600 => '1 '.t('hour'),
10800 => '3 '.t('hours'),
21600 => '6 '.t('hours'),
32400 => '9 '.t('hours'),
43200 => '12 '.t('hours'),
86400 => '24 '.t('hours'),
172800 => '2 '.t('days'),
259200 => '3 '.t('days'),
345600 => '4 '.t('days'),
432000 => '5 '.t('days'),
518400 => '6 '.t('days'),
604800 => '7 '.t('days'),
691200 => '8 '.t('days'),
777600 => '9 '.t('days'),
864000 => '10 '.t('days'),
950400 => '11 '.t('days'),
1036800 => '12 '.t('days'),
1123200 => '13 '.t('days'),
1209600 => '14 '.t('days')
),

In the D6-version I would like if it could be standard.
