Real name is always shown in section ‘Public information’

[Frigory33]

Whether or not we decide to show our real name, it is shown in the ‘Public information’ section, which is a bad thing I think.

Formerly, france-ioi.org allowed to show only the first name… It might be good to have 3 choices:

• Do not show real name
• Show only the first name
• Show full name

Well, some users tell their first name in the ‘Presentation’ field.
