form submission fixes

http://127.0.0.1:8000/eden/deploy/alert/1/recipient --> Add Recipient, Create Staff Member popup does not gets submitted +  Required fields for fire module
Good catch, although one must dig deep to hit the problem ;) 

None of the regular users (and they do use it intensively!) has hit this problem so far - which is simply because they never see that "Add Member" button (as in: they are not normally permitted to add new staff members). 

I guess the button shouldn't be there ;)
