A couple of requests for the Render HQ Snapshot render popup

Just add two simple things:
1.) Show the name of the camera currently being rendered. (Helps to know where you are in the queue if you're doing a large batch)
2.) Add a "Skip" button so you can just cancel the current camera render andmove onto the next camera without saving. Sometimes you may notice something wrong with a particular view and you just want to skip that camera and come back to it after you fix it but continue rendering the other cameras.
