Comment:

 What it does:
  * New option 'wrapDateLine' on the base layer
  * Wraps zoomToExtent
  * Wraps getLonLatFromPixel
  * Function 'adjustBounds' on layer does wrapping
  * Moved adjustBoundsForGutter inside adjustBounds
  * added calls to adjustBounds in all the getURL functions which can
 support it. (Grid layers, mostly.)

 Limitations/expectations of this patch:
  * It is expected behavior that the layer's getPixelFromLonLat will not
 wrap. This means that if you are looking at Australia and Hawai'i, and you
 place a marker at 175, it will end up visible or not visible depending on
 which side of the date line you're on.
  * Vector drawing across the date line is not supported. (Your mouse will
 'snap' to the other part of the world.)
  * Requests which cross the date line are *not* wrapped, so they will
 request content outside the world if it does not divide evenly.
