Set text and color of Gateways Widget Status

getstats.php calls functions.inc.php get_stats(), which calls get_gatewaystats().
get_gatewaystats() now returns the text for each field and an optional color separated by "/" - "text/color" e.g. "Online/#90EE90"
Parse the the new format, separating out text and color.
If color is specified, then also set it with jQuery to css.
