Title: Fix lineplot hittest

Fixes behavior of LinePlot.hittest in some cases so that it always returns None or a point rather than an index to a point. Also updates the hittesting code to check the actual lines of the plot instead of kind-of checking one line segment and the points, and adds an example to demonstrate this to the demo.
