T-log won't load when Arc16 power readings are inaccessible

The issue seems to stem from Arc16 hanging on something, and the Nokogiri command to scrape the XML from the webpage hangs forever. Namely, this line

doc = Nokogiri::XML(open('http://opdesk.wrek.org/engineering/arc16xml.php'))

never times out. Even though it is wrapped in a try-block. So we need to wrap it in some timeout thing.
