Confirmed the problem - I think its linked to how the map pane determines the full display extent

The problem was that the map pane's cached fullExtent envelope was not being properly updated when the second and subsequent map layers were added. Fixed so that the reset action now works properly and the following behaviour applies:

* If the map display is at full extent and a new layer is added the display zooms out (if necessary) to include the newly added layer.
* If the display is not at full extent (e.g. zoomed in to existing layers or panned to one side) the display area is not changed automatically when the new layer is added.

Changes committed to trunk (r35085) and 2.6.x branch (r35086)
