Supports multi-line MOTD messages

Allows a Gerrit administrator to display a multi-line
message by using the Git-style config string lists.

Very useful for adding banners, dividers, etc.

Example:
  [gerrit]
       motd = *************************************************
       motd = Gerrit User Summit 2015, 7th-8th Nov, GooglePlex
       motd = Register Now at http://goo.gl/forms/fifi2YQTc7
       motd = -------------------------------------------------
       motd = Hurry up, registration closes on Oct 1st.
       motd = *************************************************
