(oops!)
- added global variable for badgeshown to prevent mulitple instances (template contains function call AND use template check is off)
- fixed output of prepend html using decode html and stripslashes. Added green background to update settings button.
19 Jun 2009 - fix for htmlspecialchars_decode causing error in wp < 2.8 (thanks @mitch_m for testing)
