REVISION SUMMARY
  Kile has ambiguous shortcuts which result in the following string used
  as KConfig key for the dontShowAgain KMessageBox checkbox:
  
  `Find in Files...Normal Fraction - \frac{}{}Alt+Shift+F`
  
  However KConfig doesn't like it:
  
  "Invalid escape sequence \"\\f\"."
  
  and the 'f' character after the slash is removed from the key, breaking the
  dontShowAgain functionality.
  
  This patch removes all backslashes from the key, before passing it to
  the messagebox.

TEST PLAN
  Open Kile, check the dontShowAgain checkbox, close Kile. Open again Kile and
  make sure the messagebox is not shown again.
