Title: [1.9] Patch to add chr to String

Fixes the following failing tests:

String#chr returns a copy of self
String#chr returns a String
String#chr returns an empty String if self is an empty String
String#chr returns a 1-character String
String#chr returns the character at the start of the String
String#chr returns a String in the same encoding as self
