Title: only use the point type's settings in the hit plugin if the point type is available

The hit plugin cannot be used without the points type as the hit circle's sizes are computed based on the points type's options. See http://jsfiddle.net/VuUVu/. If we remove the points graph type, moving the mouse over the chart points causes a TypeError :"Cannot read property 'hitRadius' of undefined".
