#48 php: right y axis legend (y2_legend)

This patch add the possibility to set a legend to the right y axis.

Here is an example of how to use this:
$g = new open_flash_chart ();
...
$y2_legend = new y2_legend ("legend text");
$y2_legend->set_style ('{font-size: 10;}');
$g->set_y2_legend ($y2_legend);

Enjoy!
