Added reset button

It’s another hack down of the OSMGeocoder control, mostly because I don’t have time to understand how to create a control from scratch. The main fault with it is that it relies on

inner.innerHTML = “<a href=\”http://localhost:8888/realISV22\”><img src = \”css/images/reset.png\”></a>”;

The bold bit will need to be replaced with the real URL for wherever the site will be used.
