Change audio autoscroll behaviour:

Browse source 
* In karaoke mode, instead of scrolling start to end of active line into view, scroll start of selection to end of line into view. This gives sensible results when horizontal zoom is great enough that the entire line isn't visible at once and the syllable is too far from the start of the line. This fixes #677.
* If the line is too long to fit in the display, always left-align it instead of sometimes left-aligning and sometimes centering. (I think the old behaviour depended on the actual scroll position.)

Originally committed to SVN as r2928.
