Fixed a misspelling in Project.js that prevented the onFailure callback from getting called when it should’ve been, started working on error handling for when adding layers, fixed a potential bug with the InsertProjectHelper, where it wasn’t setting the includeDefaultLayer and defaultLayerVisibility in ArbiterProject
Fixed a bug in Project.js that caused the getLayerSchema success callback not to get called.  The counters were not getting reset, so the layerFinishedCount never equaled the layerCount after the first time layers were added.
