Subject: [PATCH] document the TZ environment variable

This adds a description of the "TZ" environment variable to the documentation so users will know it exists and works with Watchtower.  I only learned of this variable by reading the comments on issue #160.

 Removes old images after updating. When this flag is specified, watchtower will remove the old image after restarting a container with a new image. Use this option to prevent the accumulation of orphaned images on your system as containers are updated.
