Fixes #276: Undefined index: HTTPS
Major change to how the zone hilighting was being done and reworked the tooltip html to make the status indicators be more inline with the text close #275
Jose was right and the flickering from the image redraw was slightly annoying.  Fixed.  Smooth as glass now and still much more efficient. #275
Added a new function in misc.inc.php - locale_number( $num, $dec_places ).  It will detect the correct separators based upon the specified locale for the system.

Converted all of the tooltip code to use the locale_number function.
