v2.1.0 - Hashids salt fix
Fix issue with generating a hashids salt. Hashids doesn't accept a binary string as salt, since the salt is converted to a UTF-8 string. In some cases the binary salt was working, but in other cases the mb_detect_encoding()
method gave an error.
When updating, please note that confirmation tokens created with v2.0 will not work with v2.1.
