JAABADetect can return predictions and not save them.

Fixed a couple bugs in JAABAPlot:
When plotting time series, the lines were not on top of the patches for me, so I slightly changed the reordering of children.
I think there were some bugs in the logic section for behavior_barchart_plot. Both tmp2 and tmp3 were getting assigned to a subrange of tmp1, when I think they should have been assigned to a subrange of tmp2 and tmp3, resp.
Fixed typo where XOffset was being called Xoffset.
