-bugfix for an issue where the map control did not revert back to the
pan control when the getfeature control was turned off.
-also fixed an issue where the "container.resize" event was being fired
even when the window didn't actually change size.  this caused some
issues with the map resizing and re-centering.
-fixed an issue where re-render of table headers caused an additional
div element to be nested.
-reverted base map projection to 900913 from 3857 to maintain
compatibility with older GeoServer installs
