Remove mb3admin.com dependancies

As a stop gap mesure i would at least block it in the dns/router, i redirected it to my webserver and i can see dozens of entrys in the logs every minute, even with all reporting, updating etc disabled!

Note, this will also disable the Plugin-Installer!

It looks like this domain is only in a few files so it should be replaceable, but I'm not sure what the implications of that are. Might be worth cloning and trying to replace every one with a dummy domain to see how that works out. If it still operates normally we can make that a permanent first step.

MediaBrowser.WebDashboard/dashboard-ui/addplugin.html
MediaBrowser.WebDashboard/dashboard-ui/scripts/addpluginpage.js
MediaBrowser.WebDashboard/dashboard-ui/scripts/supporterkeypage.js
MediaBrowser.Api/StartupWizardService.cs
Emby.Server.Implementations/Security/PluginSecurityManager.cs
Emby.Server.Implementations/Updates/InstallationManager.cs

Does blocking it in /etc/hosts cause any trouble?

If anyone wants to take a go, I've replaced all the references with mb3admin.local in my repo, you can have a try if you want to.
