I don't install usercss styles much, but I just noticed that the regular button active state was being applied on click. Figured I'd give it its own active state, so I restyled them to use the same transparent background-image method for a gradient. This way, they can have regular transitioned hover states with color/background-color instead of a filter on the whole button, which was kinda odd. Also used the same vertically inverted background-image for active state, similar to what we use for regular buttons.
The goal was to fix active state and use different CSS in general, while making them look pretty much the same as they did. I think they're good, but I'm open to any suggestions. Also not sure about disabled state. I see some code for it, but the three states seem like they cover all possible states to me. Not sure why it'd ever really be disabled.
