[Maypole] catching DB errors

[Toby Corkindale]

Hi,
During the test/debug/fix process, I frequently am thrown DB errors, such as
when trying to insert a record is a duplicate but has a unique index upon it.
(eg. id serial primary key, username varchar(32) not null unique)

The DB errors currently go to the apache error_log, and the user sees a 404
Page not found error.

It'd be nice to present a page saying "Sorry you hit an error:" and then
displays the error message, at least, for our testing purposes.

What would be the best way to go about this in Maypole?

I suspect it'd involve creating a custom Class::DBI _croak() function in the
model classes, but I'm not sure.. What do you think?

thanks,
Toby
