[html-formfu] Feature request: Repeatable delete from model behavior

[Greg Coates]

As far as I can tell from the documentation, the only way that a row can 
be deleted from the model (database) when using a Repeatable is by using 
the 'delete_if_true' attribute along with a checkbox.  There's no way to 
automatically update the model if rows are removed from the Repeatable 
using javascript.

It would be really great if rows could be deleted from the model if they 
are no longer present in the Repeatable.

Is this feasible without ridiculous amounts of work.  I'd be willing to 
tackle this myself, but I'm afraid I have a long way to go in order to 
come up to speed with the FormFu internals.
