Make Character class>>separators and Character class>>allByteCharacters return strings instead of Arrays (since there is no good reason to use arrays and it solves the immediate issue observed in Mantis #7564). Also provide CharacterSet>>asString to enable its use in concatenation (i.e., '/', CharacterSet separators).
