fixing the background color property for action sheet buttons
fixing the background color property for action sheet buttons

The background color wasn't being applied correctly due to the class name being incorrect. I changed the class name to include -color- to fix the issue. I also noticed that the non popover option for the action sheet was using the color variable instead of bg variable. I changed it to use the bg variable just like the popover version of the action sheet does.
