    browser-plugin: Set windowless mode and don't claim to need XEmbed
    
    NPAPI plugins are windowed by default, so we need to set
    NPPVpluginWindowBool value to FALSE on startup. This way the browser
    will not create a GtkSocket for a GtkPlug that we are not going to
    create. It doesn't make sense to claim that we need XEmbed either.
