title: Escape Dollar sign ($) in Jenkins emails
body: <p>In the content field of "Editable Email Notification" (Email-ext plugin in Jenkins) I would like to escape the $ sign so I can email "$WORD" which is an environment variable of the job (defined using Build Environment->Properties Content) without it being expanded to anything.<br>
  Backslashes doesn't seem to do...</p>
  
  <p>Thanks!</p>
