Add length limits to text input fields (#938)

- Limit nickname to 32 characters
- Limit first name, last name, group name, distribution list name to
  256 characters

In case multi-byte characters are used, the values will be rejected by
the apps with the error `valueTooLong`. I don't think we need to add
special handling / validation for these rare cases.
