Some cleanup on the batch mode stuff. Make it more explicit in the
showexp page that its a batch experiment, by the menu options. Same deal in the swapexp output, plus some other minor cleanup. The only bug I found while trying to figure out the batchmode problem reported this morning by the FileMover people, is that the cancelflag is not cleared after swaping a running batch experiment out, so even after reinjecting it into the queue, it will not run. Still, that does seem to be what the FileMover people reported.
