Title: Image charts

Adds image charts and the #uri method, which returns a URI for getting a static chart image through Google Charts API. Includes specs. See http://code.google.com/apis/chart/image/docs/making_charts.html for details.

e.g.:

```
GoogleVisualr::Image::PieChart.new( data_table, options ).uri
=> #
```
