Added nycpedia specific change
Added functionality to show infobox on hover.

Uses mouseover and mouseout to show infobox.

TODO: Make this customizable
Added labels for all shapes.

Uses gm3-util-library for maplabel.
Displays it on the south east bounds of the shape (not in the center)
Removed link or title/text and made it AND for MapEditor

Wouldn't work without a change in the manipulation of parameters on server
side.
