2.0.0

A customized and backward incompatible version. Changes are:

• the default value for the environment variable JOB_RUN_TIME is removed to signal there is no server runtime limit — the extension then displays the time elapsed since the server started
• JOB_RUN_TIME is interpreted in seconds instead of minutes to align it with the --max-age flag of the jupyterhub-idle-culler
• enable users to setup a notification to get notified by their system notification system before the server terminates
• rounding of the displayed time
• visual changes: no red text and no blinking, but two boom icons around the remaining time if runtime limit gets close
