Legend enhancements

[Guy Rouillier]

Please see https://sourceforge.net/tracker/index.p ... tid=115494. I've made some changes to Legend.java and StandardLegend.java to provide more control over legends. Specifically, I've separated the concepts of orientation and placement, introduced wrapping for vertical legends, and permit control over how many columns and rows appear in vertical and horizontal legends, respectively.
