Context menu disable option

[Marek Lewandowski]

<p>We need an option to disable our custom context menu, even if the plugin is loaded. The thing is that <code>contextmenu</code> plugin is required by plugins like <code>tabletools</code> or <code>liststyle</code>, where it&#39;s the only way to see the features added by the plugin.</p> <p>If we&#39;d remove it from <code>required</code> property, this plugin would not be automatically picked by our online builder, so that&#39;s a no-go.</p> <p>But some customers provide custom implementation of UI, where context menu is not needed.</p>
