Subject: [PATCH] Reorder reverse caps characters table for string lower case
 conversion

The binary search algorithm used to lookup character codes in the table
relies that the data must be ordered. This fixes `to_lower()` string
method to convert upper case to lower case properly, so that the
algorithm doesn't terminate prematurely.
