this commit adds two new helper functions to use uuid information from the config.xml.

1) get a tagname by uuid, or __not_found__ if uuid is not in the config.xml
{{ helpers.getUUIDtag('a8da740a-046a-4994-8535-89f5fff47393') }}

2) returns an object by uuid, ready to use
{{ helpers.getUUID('a8da740a-046a-4994-8535-89f5fff47393').number }}

(mvc model) add ModelRelationField type, creates a optionlist populated by array type items from other entities.

Example definition from trafficshaper model, relating a pipe to a rule.

                <target type="ModelRelationField">
                    <Model>
                        <pipes>
                            <source>OPNsense.TrafficShaper.TrafficShaper</source>
                            <items>pipes.pipe</items>
                            <display>description</display>
                        </pipes>
                    </Model>
                </target>

// create a new model
$model = new Model();
// link model to support class
$grid = new UIModelGrid($model->container->arrayTypeObject);
// fetch data and return into array which our frontend grid component can use
$result = $grid->fetch($fields, $itemsPerPage, $currentPage, $sortBy, $sortDescending, $searchPhrase);

o Regenerate all dhparam files.  (Looksie, we don't have under 1024!)

o Make beast mitigation the default, been around since 2011.

o Tweak the cipher settings via recommendations below.

Open points are the zapping of 1024 bit dhparam and how we should
handle dhparam shipping in the future.  Please write in to discuss.  :)

Integrate uuid generation into the core of the model system so items are uniquely identified and can be directly accessed using their uuids.

For example:
// set recurring pipe item to 1001
$model->setNodeByReference('pipes.pipe.86f19d48-bc91-4c70-a81c-e05cdd3a4372.queue', "1001");

// echo the contents back
echo $model->getNodeByReference('pipes.pipe.86f19d48-bc91-4c70-a81c-e05cdd3a4372.queue');
