Filter plugins based on deny list

[gabrielsclimaco]

Filter plugins that are rendered based on a deny list in components data.

I had to change the way the plugin component get the plugin object in order to make it work; I did by passing the plugin object via prop.

I also took the liberty to fix PluginsPanel indentation.

Here's the ending result

If there's more plugins that should be added to the deny list, just let me know.

closes #223
