Made a bunch of changes to fix the distance bearing plugin, and to make it more generic
Made the gap versioned editor more dynamic so that it gets the store name from the specific layer and checks to see if it's a geogit layer before adding the history tab to the feature info popup up.  Currently, the requests to get the store name and check to see if it's a geogit store are being sent for every getFeatureInfo request.  At some point we can fix this so that the requests are sent once when the layer is added or something and then that info is kept track of
