The zoom control allows for zoom in/out links that can be styled with CSS.
Note: This change was originally captured in #269. It involves nice additions thanks @ahocevar. The changes were unintentionally merged and then reverted with fb3caf1561, so the history of commits is not immediately apparent (though still likely there somewhere due to the magic of git).
Previously, a map could not be destroyed if it included a permalink control without an "element". In addition, a permalink control could not be destroyed if it didn't have a reference to a map.
If a map is configured with a permalink control and a center, the permalink control tries to work with the map center before setCenter is called. This sequence assumes that the map center will already be a LonLat. This fails if the map is constructed with a coordinate array. Safer move is to convert center to LonLat before controls are added.
In setMap, the layer gets the map's projection if it doesn't have its own. And since a layer can have a different SRS code than the map (but a compatible one, i.e. with OpenLayers.Projection.transforms[mapProj][layerProj] being OpenLayer.Projection.nullTransform), the axis order can be different.
This allows us to simplify the map and layer configuration, because now the projection also defines defaults for maxExtent, maxResolution and units.
This change also adds transforms for SRS aliases for EPSG:4326 and centralizes axis order information in OpenLayers.Projection.defaults.
Whitespace fixed from patch, and removed docs for beforefeatureselected and featureselected events because they are fired on the layer, not the control.

For PanZoomBar, this fixes the slider behavior. Now the buttonclick listener argument also includes a buttonXY property, and PanZoomPanel does not need an Events instance for the zoombarDiv any more.
For Panel, this fixes events for panels outside the map. Just setting the element on the Events instance was no longer enough after e70569b2bb. Events::attachToElement is now used, and it needed to be modified to also work if the Events instance had no element previously.
Finally, I renamed the button property of the buttonclick listener argument to buttonElement, to not confuse it with the browser event button property, and added some more tests and documentation.
This change involves removal of the map's eventsDiv and introduces an OpenLayers.Events.buttonclick component that adds a buttonclick event which makes sure that only events that are not related to clicking a button propagate. This allows button controls to be on the map's viewPortDiv again.
