Legends are too crowded and overwrite with more than a handful of datasets

Pasting Jabber comment from Ray:

http://code.google.com/p/gwt-chronoscope/issues/detail?id=41

"the LegendAxis.getHeight() routine is the source of the problem of overflowing 
into
the chart. I'm not sure why, it delegates to renderer.getLegendLabelBounds() 
which is
supposed to compute a bounding box of all of the legend labels, + 20 pixels for 
good
measure.
there are order-of-operations stuff to consider, when this getHeight() method is
called, has plot.getInnerPlotBounds() already been properly computed (the width
property accounts for axis on left and right?)
1:39 I could see a situation where getHeight() called before the width of the 
plot is
available would assume that more labels could fit than really could, so
getLegendLabelBounds() would return something smaller than if called later"

Resolved in r182 (see check-in comments for details); logic in 
getLegendLabelBounds()
for determining bounding box for legend axis was inconsistent with logic for
positioning the labels in drawLegend().  Tested with varying number of datasets 
as
well as varying dataset name lengths.  See attached image for "before and after"
screen shot.

Will open up another issue (if one doesn't already exist) to address the issue 
where
the legend labels "skip around" due to the numerical range values that 
intermittently
get appended to the legend labels in correspondence to the user's hovering 
activities
(e.g. "My Dataset" vs. "My Dataset (1.2345)").
