// Description: This is my attempt to fix a bug in the Google personalized
//      home page theme system.  In my experience, the server selects
//      the wrong time (GMT, I think) the first time your personalized home
//      page is loaded per browser session.  This code changes the css href
//      based on your current system time.
// Changes:
// 0.2 - added: springscape, summerscape, and autumnscape
