FileOperation: Accept multiple source arguments

Browse source 
You can now list multiple files or directories and they will all be
copied to the destination. :^)

Note that this means you can pass the same file or directory multiple
times. It runs fine, just means that it does unnecessary work. But
figuring out if a file is already queued is probably more hassle than
it's worth, if it's even possible at all due to symlinks.
