LiveDataSeries - not possible to have update not returning data

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Create a chart with a live data series
2. In LiveDataSeries update method, return null

What is the expected output? What do you see instead?

I was expecting returning null was going to not update the chart but it raises 
a NPE. It could be good to be able to skip an update occurence (because data is 
not available yet for any reason). I guess just checking for null before update 
in Wicket6LiveDataAjaxBehavior could do the trick.

What version of the product are you using? On what operating system?
1.3.1 (wicked-charts-wicket6)

Thanks !

Additionally, it could be good to set the init method of 
com.googlecode.wickedcharts.highcharts.Chart protected instead of private to 
allow easy override of ChartBehavior :-)

I added the possibility to return null for the next version.

For overriding ChartBehavior, i added the method createChartBehavior() to the 
Chart class.

Thanks for the ideas!
