Networkerror

I've restructured the script to do the wget first and detect any fetch errors; if there is one it skips the other fetches and logs the error. I've only tested it on the first item in the sites list, which generates an error because of the files produces a filename that wget thinks is too long; so there's work to do to prevent that kind of error from derailing the process. Once that's done, though, I think it would be worth adding email notification of errors, to detect when legal action by EMP causes a posting to disappear.
