Issue 8719: Add basic support for :active selector

<!-- Please describe your changes on the following line: -->
Added toggling of active state for element and parents on mousedown/mouseup. Active state is removed when mouseout. (hover)

- As with my other PR i'm struggling a bit with the automated testing. I've added a manual test case and found quirks-mode/active-and-hover-manual.html which - aside from also being a manual test, is functional in Firefox but does not render correctly in Servo.
- Not implemented: In Firefox, behaviour differs with a <!DOCTYPE HTML> and an anchor does not lose it's activation on mouseout; whereas a button does.
