Clean up a few more project settings for the ArcGIS upgrade
Change the layer loading mechanism to fix the things that broke when ArcGIS updated to 10.x (hint: a lot of it).
Play around with adding some padding to the region. Currently this is encountering a bug where, if a single annotation is passes, the min/max points are the same and ArcGIS has no idea how to handle it.
ArcGIS changed how graphics layers get their spatial references in 10.x. Now they seem to take on the spatial reference of the first object added or the map view it's added to.

ToDo: Implement the layer delegation protocol so I can listen in on when it's safe to start adding things to the graphics layer.
Add some descriptions to the annotation types in order to flesh out their behavior a bit more. Also added a couple of optional properties to the interface to control elements of the poly* objects line width and fill/stroke colors.
