quick fix to bower.json
stackedAreaChart: Added a new stack offset mode, called 'stack_percent'. It behaves like 'expanded' mode, except the chart doesn't rescale to 100% when removing a series.

Update bower.json
Fixed a bug in stackedArea where the seriesIndex being passed to dispatch.areaClick was not correct.
What ended up happening is, when clicking on the area, the wrong series would get selected.
In line and stackedArea, removed the exit() transitions. They cause too many bugs and are not necessary for chart transitions to look nice.
Updated version to 1.1.14
