[134f-gr] Released Polymaps and OpenLayers hover and click examples

[Roy Hyunjin Han]

Here are two demos on making your maps more interactive.

* Polymaps hover and click demo
http://georegistry.org/examples/polymaps
- Fast and beautiful but will not work in Internet Explorer
- Thanks to Mike Bostock for hints on SVG interactivity

* OpenLayers hover and click demo
http://georegistry.org/examples/openlayers
- Slower but functional
- Thanks to Andy Doro for feature styling

Here is an older application that also uses mouse hover and click
events in OpenLayers.
