[Users] Base Map Layers all get loaded on map load

[Dan Ramage]

I pinpointed the exact cause of the issue, added a ticket, then realized I
was the culprit. The ticket I created is #231, and I've since changed the
status to wontfix.
Basically I was calling OpenLayers setCenter function before I was creating
my viewport. I basically just ported my basic OpenLayers code over to the
GeoExt framework, calling it in Ext.onReady function. This is a case of
calling a function before it is safe to do so I suppose.
