Ignore accent while searching for users on People page

[gnyiri]

There are some complaints at ELI about searching users with special characters in their name (e.g. Ä). The lookup will fail unless the special characters are entered properly.

In PSQL it is possible to create a collation for ignoring accents and user this collation in the associated sql query.

What do you think?

Doing it at the db layer won't affect stfc as we fetch all our users from a external service but seems like a very sensible suggestion.

No necessariliy on the DB layer but this improvement would be fine anyway.
