SocialAPI: Allow Multiple Workers

Summary

Enable social.allowMultipleWorkers by default from Firefox 27. This allows running more than one frameworker at a time, and frameworkers to use remote browsers (e10s) the same way that thumbnailing for new tab is now done. Without these changes, only the 'active' social provider can have a running worker. This prevents implementing communication applications as a social provider, as incoming calls wouldn't be received when the social provider is not the active one.
