Update bank files - Fixes #1

This pull request updates the bank files to mirror the files in the original implementation (http://cpansearch.perl.org/src/SBURKE/Text-Unidecode-0.04/lib/Text/Unidecode/)
``\$`` and ``\@`` are wrong here. The ``\`` in the Perl code is the escape char because ``@`` and ``$`` are special chars (it should be checked in all bank files)
