2.0 r11
- don't overwrite widgets list if table already exists (in case an external lib or addon registers a new widget type)
- headers, descriptions, submenus and custom widgets now have the ability to update their text when the panel and other controls refresh (simply change the name/text in the controlData table)
- custom controls now have the ability to refresh with other controls and your panel - there is a new optional field in the data table called refreshFunc (when the panel refreshes, this function will be called)
