This hook providers basic weechat deploy support. The environment
variables WEECHAT_PEM and WEECHAT_HOME are respected, and otherwise
default to ~/.weechat/ssl/relay.pem and ~/.weechat/ respectively unless
set.
Upon a successful deployment, this script then attempts to issue a
'/relay sslcertkey' to weechat using the fifo plugin when configured
and available. See script headers for more information.
