[html-formfu] HTML-FormFu-DBIC

[Carl Franks]

I spoke with zby a while ago about HTML-FormFu-DBIC, and this is what
was agreed:
At the moment, fill_formfu_values() and populate_from_formfu() are
copied in both DBIx-Class-HTML-FormFu and HTML-FormFu-DBIC.
So what we'll do is have them only in HTML-FormFu-DBIC as exportable
functions, and have DBIx-Class-HTML-FormFu import them.

I've been making updates to DBIx-Class-HTML-FormFu, so I'll now start
to move the updates made to HTML-FormFu-DBIC back into
DBIx-Class-HTML-FormFu - and add tests, as there doesn't seem to be
any for the changes to HTML-FormFu-DBIC.
Once that's done, I'll move the latest functions and tests back into
HTML-FormFu-DBIC, and make DBIx-Class-HTML-FormFu import them from
there.
(Hope that all makes sense)

So it'd be a good idea, if anyone wants to make changes to either of
these packages, if you could bring it up on the list so that we can
make sure we don't step on each others toes.
