    New "rawsort" attribute, fixed sort attribute whitespace problem.
    
    New "rawsort" attribute allows you to pass a verbatim sort to the SQL database
    without any parsing by Interchange.  This allows you to do things like this:
    
    Options Simple sort CAST(o_sort AS int)
    Options Simple rawsort 1
    
    ...the above would sort option widgets based on teh o_sort attribute and force
    a numeric sort.  There are numerous other possibilities of how you might want
    to use this as well.
    
    The existing find_sort routine returned the "ORDER BY ..." without any leading
    whitespace, and was tacked onto the end of the sql query in Simple.pm without
    any trailing whitespace thus causing a syntax error in the generated SQL.  This
    is now fixed by adding a leading space onto the returned value of find_sort().
