zed: support subject as header in zed_notify_email() 
Some minimal MUAs don't support passing the subjects as cmdline option.
This commit checks if "@SUBJECT@" is missing in ZED_EMAIL_OPTS and then
prepends a subject header to the notification message.
Also set a default for ${subject}.

README 

Shell scripts are the recommended choice for ZEDLETs that mostly call
other utilities and do relatively little data manipulation.

Shell scripts MUST work on both bash and dash.

Shell scripts MUST run cleanly through ShellCheck:
  http://www.shellcheck.net/

General functions reside in "zed-functions.sh".  Use them where applicable.
