 * ConnectionTest
 *
 * A more intelligent check to see if we can connect to Splashbase or not.
 *
 * This class checks whether or not we can connect to the Internet, and
 * if we can, whether we can connect to Splashbase itself. This is used by
 * our admin notice function to check whether or not we should display a notice
 * to users warning them of issues with Splashbase.
 *
 * The purpose of this is to avoid useless bug-hunting when images don't work.
