Export the new Conditionals feature of Webform 4.x branch

The conditional actions associated with Webform 7.x-4.x are already in the export, there was just nothing in the import process to accept and save them. adding the following line to webform_share_components_update_form_submit will import the conditional statements if they exist.

  $component['cid'] = $cid;
      $component['nid'] = $node->nid;
      $node->webform['components'][$cid] = $component;
    }
    
    $node->webform['conditionals'] = isset($webform['conditionals'])?$webform['conditionals']:array(); // <--THIS IS THE LINE THAT NEEDS TO BE ADDED.

    // If requested, re-add the existing components rather than allowing these
    // to be deleted. Existing cid values are safe to reuse.
    if (!empty($form_state['values']['keep_existing_components'])) {

It should be around line 157 of webform_share.module.

Note: this is a quick and dirty method. There should probably be some checking to make sure component IDs match up...

I think there should probably be cid matchup indeed. Not much though. I imported a webform with 20 conditionals only one of which had a mismatch on a component ID.
Unfortunately I do not seem to be able to produce a minimal testcase / reproduction of the problem.

#1 works fine if you have not deleted any fields above the elements you are running conditions on. If you have deleted some webform fields, it will miss. I tried to use the above to move a form with 50+ conditional statements and 120+ conditional rules.

My content creator had deleted a field early on. Every field condition broke. I was able to update the source field in the webform_conditional_rules table via sql query but I eneded up having to manually set the targets in the webform_conditional field through the web admin interface. I don't intend to do that again.

I'll try making the matching work and submit a patch if I ever need this again but I'm probably just going to recommend that my content creators set conditional statements live in the near future.

#1 works when both import checkboxes are unchecked. This is all we need for now, so attaching a patch for tracking. If you need to check the CID on existing webforms, more work would need to be done.

Tested #4 and it seems to work fine for this needed functionality.

Committed.

Cheers
