title: Custom webform-mail template in Drupal 7 does not work
body: <p>I'm trying to customise the webform email template for a specific webform following the steps in THEMING.txt, but those changes aren't being reflected in the form's default email template. I may have made a mistake in multiple places so I'm going to walk through my steps and hopefully someone will be able to spot what I did wrong :)</p>
  
  <p>1) I copied the webform-mail.tpl.php template from /sites/all/modules/webform/templates directory over into the /themes/mytheme/ directory. Is that the correct place to drop it?</p>
  
  <p>2) To test it, I simply changed some of the text. So I just changed 'Submitted on %date' to 'Entered on %date'.</p>
  
  <p>3) I then renamed the page to webform-mail-1226.tpl.php, where 1226 is the number I see in the url when I go to edit the webform.</p>
  
  <p>4) Then I tried to clear the cache, but I think this is the step I did wrong. The THEMING.txt file says to visit admin/settings/performance, but that path doesn't seem to work/exist for me. What I tried instead was admin/config/development/performance/ and then cleared the cache with the options here. Am I supposed to go somewhere else to clear a different cache?</p>
  
  <p>5) I then went to the emails section corresponding to this form, and when I either go to an existing email or create a new one, the default email template does not reflect the changes I tried to implement.</p>
  
  <p>Does anyone have any ideas why this isn't working? Thanks for your time and help :)</p>
