Add sortorder parameter to selectForFormsList method

there are a problem on many extrafields list : we can't sort list by decrease and sort from a specific fields since we have add an sql prevention on filter based on : separator (who is used to separate parameters)

@eldy  i propose to remplace on extrafields parameters the : in the sql injection prevention by another caracters, by exemple the ; or the § , and replace it after having explode all the parameters
