geometries don't have events

[tschaub]

creating a new geometry gives you an geometry.events property. This is null, but I think it encourages people to tack on events here. I don't think we want to support this (but I could be wrong).

Currently, these events are only accessed in geometry.destroy() and in the geometry tests.

The following patch gets rid of all trace of geometry.events. I'm open to discussion on leaving this in - perhaps we do want to give people a place to put events, and to have them handled properly on destroy. But since we're not using it now, it seems like a liability to me. Keep in mind that it is not trivial to get at the dom element associated with a rendered feature - so I can't see how people are going to assign listeners to browser events for a geometry that readily.
