make height a geom_turn() aesthetic

[mdingemanse]

Sometimes you want to map some other statistic to height. In the example below, the higher (and more overlapping) the rectangles are, the more competitive the speech in that fragment is. We do this by adjusting the height of the box by some multiple of load (a measure of the degree of competitiveness in a 10 second window, already available in talkr-formatted data).
