Item10477: no way to create a meta object, attach a dataform and set field values programmatically

It came as a surprise that there's no way to do this easily:

(pseudo code)

   my $topicObj = new Foswiki::Meta($session, $web, "NewTopic", $textWithoutMeta); 
   $topicObj->addDataForm($web, "SomeForm"); # we've got $topicObj->putKeyed('FORM', "$web.SomeForm") ... maybe that's enuf, but still rather low level
   $topicObject->putFormValues(
      FieldName1 => $value1,
      FieldName2 => $value2,
   );

The bits to do that are spread over different places:

• Foswiki::UI::Save holds the code to establish a DataForm within the Meta object
• Foswiki::Form::FieldDefinition holds the code to populate a DataForm with values taken from a $query.

The rest of the code assumes a DataForm is already attached to a topicObj. Creating one from scratch is not possible as is now.
