[Koha] gonenoaddress, lost, etc.

[Owen Leonard]

I'm looking at the borrowers table trying to figure out how some of the 
'status' columns are used.  These seem to include

gonenoaddress (no current valid address on file)
debarred (barred from checking anything out)
lost (card has been lost)

...But how are these set?  And is there no way to override the block if you 
want to check something out. Our current system presents the information and 
asks if you want to override.  That seems to be the best approach since it 
allows you to complete the patron transaction without doing, well, whatever it 
is you have to do to remove the status.
