proceesor, storage: better error handling; no interrupting pipeline

- print clear stack trace using timbre when capturing exceptions
- don't pass nil to url/normalize; if url/normalize gets a nil, instead
of NPE, it now returns an empty string
- capture exceptions in processor pipeline to keep it from dying
- http.downloader now checks response status instead of blindly
downloading anything
