This commit makes it possible to select the sort mode whenever we invoke an operator.

It's needed especially for the menu entry "recover auto save" where you'd like to have the files sorted by date most of the time but it could be useful in other places too.
There should be no functional change in other areas, I just added the missing parameter (FILE_SORT_ALPHA).

Was a request from @sebastian_k at #BCon13, so at least one guy needs it ;)
