"Scheme Rights" forms/reports section

[robgaston]

As per #121, the license section in the mockups should be renamed "Scheme Rights", which will include the type and holder drop downs. This tile is cardinality 1 and will be the parent of the rights statements. this will use the "Rights" nodegroup

The "Right Type" node will be a "reference" node, and there is overlapping work on this widget which should be reused for #147. The "Right Holder" node will be a "resource-instance" node and there is prior work here in #129/#149

this nodegroup is cardinality 1, which means it will be handled similarly to #128 in terms of form interaction and reporting

We can then add another section for "Scheme Rights Statements" which can manage the fields that make up the right_statement (cardinality n). This section will be similar to the "Scheme Labels" section, so this work should be done in a separate ticket when #146 and #147 are completed.
