Optionally disable timestamps

[silverbucket]

When a node process is managed by systemd, systemd already provides timestamps in addition to the automatic prepending of timestamps by debug when not in a TTY. Therefore each line has double-timestamps.

DEBUG_NOTIMESTAMPS=1 or something similar would be a great feature to have.

Timestamps show up in PM2 also. I am interested in toggleable, namespaced logging, not timestamps.

This is an issue in Heroku as well. Please check out the PR to solve this
