[ESS] Problem with `ess-sas-global-unix-keys` and "File mode specification error: (void-variable ess-ac-sources)"

[Vitalie Spinu]

SAS uses ess-mode which calls ess-load-extras. I don't understand why
this didn't pop up earlier. ess-ac-sources indeed wasn't declared as a
variable. Strange.

Fixed. Thank you for the report, 

  Vitalie
