Fix missing properties editor update when changing 3D View camera

Actually two errors here:
* Properties editor wasn't refreshing on (NC_SCENE | ND_RENDER_OPTIONS) notifiers
* Was using notifier info bits wrongly, needs to send two separate notifiers

Decided to remove ND_RENDER_OPTIONS rather than adding properties editor scene context refresh for it, this is more than a render option change.
