[html-formfu] HTML::FormFu::Model::DBIC documentation patchlet

[Nigel Metheringham]

I got caught out by the requirements on a has_many relationship that  
there has to be a single column primary key on the related table (so  
that this can go into the hidden form field).

I've tried to add to the documentation for this, but am not happy I  
have clarified things (rather than made them more clumsy).  
Suggestions, rejections or acclamations welcome for the attached  
patch...

BTW in this case I had effectively a link table (so set up as though  
it was a many-to-many linking table) that had an additional piece of  
information in it, so wanted to use a has_many type relation to edit  
it - think of a order <-> products relation where its a many-to-many  
but each link has a quantity attached.  In this case the primary key  
of the link table was a multicolumn key (order, product).  I think  
this is a valid usage case, so the inability of the form model to  
handle it is a bit of a pain.

	Nigel.
