Issue 110328

In the dutch translation, the message when trying to create a table without a 
primary key yields a confusing message. I'm pretty good with databases, but I 
can't currently make out what the message tells me exactly, apart from lacking 
a primary key. I'm not sure whether the message tells me I need either a unique 
index or a primary key, or that those two are the same thing (because of the 
quotes around 'unieke index').

Suggested rewording:

---
Geen primaire sleutel ingesteld.

Om records uniek te kunnen identificeren vereist deze database een zogeheten 
'primaire sleutel'. Voor deze tabel ontbreekt de primaire sleutel op dit moment 
nog, waardoor u geen gegevens in de tabel kunt invoeren.

Wilt u nu een primaire sleutel definiëren?

Also consider adding a Help button. For a lay-person, this is exactly the kind 
of error message you shouldn't present without at least offering to help them 
understand what they're doing.
