Altered:
- CLSNetworkDirectorySynchronizer was being built in the wrong directory. It was going into build/build, fixed in the internal.pro file.

Added:
- A check during startup in SGMAppController. If there are no entires in the AMCameraURL table, then create a default one for the normal camera.

Removed:
- Commented out an ErrorMon debug in AMGraphicsVideoSceneCopier. I really don't think it's needed.
Merge pull request #994 from acquaman/Issue993

I also fixed that database upgrade issue on SGM (my own doing, of course). In the process I added some extra information to the error monitor message that gets produced. It should be easier to identify these types of bugs moving forward.
