[Nitro] Problem with forgien key constraints

[rob]

It isn't really important what the constraint names are as you can  
examine the constraint definitions to see what should and shouldn't  
be there, I tried to give them descriptive names in the same vein as  
the join table naming system (for people who care to meddle with the  
database manually) but it's not necessary, they could be named anything.

Nice idea.
