- Allow escaping any character in a character set.
- Use RxsCharacter instead of RxsPredicate for single character escapes like \r, \n, etc.
- Use nil instead of #epsilon for the extremal stream element in RxParser.
- RxParser >> #next returns the value of lookahead. Use it where it makes sense.
- RxsPredicate's class variables' initialization is thread-safe.
- Reinitialize EscapedLetterSelectors in the postscript.
