[Html-widget] DBIx::Class::FormFu

[Carl Franks]

Another formfu update!

I've created a DBIx-Class extension, available in svn here:
http://dbix-class-formfu.googlecode.com/svn/

The only noticable usage differences from dbix-class-htmlwidget are:
* the method-names are now fill_formfu_values() and populate_from_formfu()
* both methods expect the $result object as an argument

Code wise, it's a lot simpler, as formfu provides the field-level
logic such as how to handle checkboxes, select menus etc, so the dbic
extension doesn't need any field-specific code at all.

The test files include simple instructions to create the sqlite
database - otherwise tests are skipped.

The most notable recent update to formfu is that $form->result() now
accepts a hash-ref as an alternative to a query object.
This helps for using formfu as a validator for arbitrary data, and
will also help to reduce the code in the test suite.

Cheers,
Carl
