Because stop date gets the start date by acquisition when no stop date is set,
scripts need to take special care that the date is actually set. This was not
the case in this script, so assignments with only a start date but no stop date
where not considered.

used to select the group in user preferences and in reports dialogs

 - fix "numeric" which was not working at all

This is horrible user experience on mobile, user can accidentally touch the
image and then get redirected to captcha.net website which is generally not
useful. As far as a I understand their conditions of use, they don't require
use to make a link to their website.

It seems this never worked, it was comparing a string received from the client
with a number from the session.
