Ordering/adding spaces does not work for document field

[tmb]

To reproduce:

• add a new field to documents.pl

        {
                name => "foo",
                type => "text",
                input_ordered => 1,
                multiple => 1,
        },

• bin/epadmin update_database_structure
• add foo to workflow in <component field="Documents"> section
• restart apache
• create new item and go to Upload stage
• upload document
• up/down and "more input rows" buttons have no effect for foo field

The Documents inputform plugin should call get_state_params() for the fields it displays. InputForm?_Component_Documents.pm.diff fixes this.

With this patch up/down/morespaces now work, BUT if there is >1 document, changing the order of foo for one document changes the order for ALL documents - similar for more input rows. The issue is Metafield.pm uses the field name rather than the basename for the up/down/morespaces param/button IDs - MetaField?.pm.diff fixes this.

However there are still problems - eg. inconsistent use of prefix parameter to MetaField::get_state_params (compare perl_lib/EPrints/Plugin/InputForm/Component/Field/Multi.pm and perl_lib/EPrints/Plugin/InputForm/Component/Field.pm) which breaks up/down/morespaces inside a Multi component.
