Create a warning inside plugin configuration when Article's manager parameter "Show article options" is disabled

[ggppdk]

Check and show messages inside plugin configuration, e.g. check Article Manager parameter show_article_options which will prevent SocialMeta TAB from showing inside article form

---

• Either create a new form element (parameter) (for better placement):

class JFormFieldSocialMetaChecks extends JFormFieldList

• or via enqueueing a message on as system event of the plugin

JFactory::getApplication()->enqueueMessage('..', 'warning');

---

So to avoid user wondering why social TAB is not showing when:

JComponentHelper::getParams( 'com_content' )->get('show_article_options') == 0

We need to add a warning message like:

'Article manager' parameter: "Show article options", needs to be enabled otherwise, plugin's 'Social' parameter TAB , will not be shown in the article form

Agreed, I didn't even know this option. I will add a notice for the superusers.
