Title: stbt.draw_text: Fade out older text

`stbt.press` uses `draw_text` to draw the pressed key name on the output
video stream for 3 seconds, and I always found it very confusing when
there were several keypresses in quick succession -- is the latest
keypress at the top or at the bottom? Now it is very clear.
