Prompt before config goes into affect

[mrek]

This one could be chalked up to user error, but may have been prevented. Tonight while one of my gbpvr machines was recording I changed the config to include another video folder (so I could view shows recorded on the other gbpvr box). This caused gbpvr to interrupt the current recording. When the service came back up it started recording the show again, but over the previous file. My wish is for a prompt to tell me that a recording is taking place and asking if I really want to enable that config or for gbpvr to see that a file is already present with a given name and append a _copy (or something) to the filename.

Thanks & Great piece of software!
