Misleading metadata processing log message

[Rodrigo Rodrigues da Silva]

After some medium is processed one gets the following message:

2014-10-17 10:24:05,320 DEBUG [mediagoblin.tools.processing] No processing callback for <MediaEntry 34: Aula1>

While developing/debugging a plugin I got this message and found it very confusing. Looking at the source code I'm convinced this message should read something like No metadata processing callback for <MediaEntry 34: Aula1>

Patch provided.

I agree, this message wasn't very clear. I merged your patch, then added a bit further clarification. "Processing Metadata" is a bit inconsistent with our later uses of the term metadata, but this happened before then. Basically this was just an indicator of whether or not there's a webhook to call.

Anyway, I adjusted the phrasing to:

        _log.debug('No processing callback URL for {0}'.format(entry))

and

    _log.debug('Sending processing callback for {0} to {1}'.format(
        entry,
        url))

That should be a lot clearer.

And thanks again! :)
