Re-fix for bug 29820: remove "Changed" from email subject line. Based on patch submitted by Stephan Niemz [faniz] <st.n@gmx.net>, r= jake, cyeh

UPGRADE NOTES: when you install this update, you will need to change the subject line in your 'changedmail' and 'newchangedmail' params from the web by running editparams.cgi.  The subject line needs to be changed from:
Subject: [Bug %bugid%] %neworchanged% - %summary%
to
Subject: [Bug %bugid%] %neworchanged%%summary%

Or whatever is appropriate for the subject you are using on your system.  Note the removal of the " - " in the middle.
