Separate log files for stdout and stderr

[cadorn]

I need stdout and stderr in separate log files. Would send pull request if I knew C.

Current signature:

require("daemon").daemonize(logPath, pidFile, ...

Proposed optional new signature:

require("daemon").daemonize({
    stdout: stdoutLogPath,
    stderr: stderrLogPath
}, pidFile, ...

Thanks!

Working with Javascript Object literals in C++ add-ons is something I am not familiar with. I will try to get up to speed and address this sometime, but I don't know when that will be.

Maybe @polotek would want to lend a hand, he's much more knowledgable V8/C++ than I.
