PIVOT-889:  Allow newline characters in Label text to do a hard line break
when "wrapText" is set true.

I think this is "what you would expect" in this case, so I'm not doing a
new style (even for backward compatibility).  If someone feels it is necessary
it wouldn't be hard to add such a style.

This is a merge of revision 1435351 from trunk to branches/2.0.x.
