Fixed issue ghiscoding#99 to support backslash inside `alt`

- Inserting a backslash "\" inside an `alt:` (alternate message) was
causing the validation to not work properly.
- Also removed IBAN support as default validator, this should instead be
validated through the help of custom validation and an external library
like arhs/iban.js
