Handled here rather than in settings.php file
$onLoadExtras = ""; and $pluginsDisplay = ""; also set here
No need to recreate the plugins array from POST'd values, now picked up
from a page load
If isset($_GET['updatedPlugins']) then update the new pluginsOptional
DIV innerHTML, no need to also check if the DIV exists
Also restart the plugin intervals upon $_GET['updatedPlugins']
No longer tacking content visibility onto $onLoadExtras
