Adding new nonverbose log level

[tatsuhiro-t]

I think it will be accomplished to log download progress summary in notice level.

Here's what I want out of aria2c logging: to be able to infer incomplete downloads from a prior terminated session, in order to figure out whether I need to invoke aria2c again.

To do that, I need (a) the path of the file being saved to (since the source may be 302 redirect, or may have session-specific gunk attached to URL, etc.); (b) enough information to then test the file on disk to see if it is complete, in something simple like wget I'd compare content-length with file size; and (c) notifications when files are complete.

At the NOTICE level we do get Download complete:. But we don't get enough information for (a) or (b); not at INFO level either.
