Title: Add hover callback to HoverDetail for receiving name of the selected series.

This patch increases the interactive capabilities of the graph.
Usage:

```javascript
hoverDetail = new Rickshaw.Graph.HoverDetail( {
graph: graph,
hoverCallback: function(name) {
console.log(name); // name of the series the mouse is hovering
}
} );
```
