Fix Swift dangling span by subclassing JFlexXrefSimple
Also: - Make SwiftXref case-sensitive, converting {File} pattern. - Escape all HTML special characters in SwiftXref. - Fix not to continue STRING after an end-quote, in case a TSTRING is actually starting. - Fix to fine-tune URI link for Swift COMMENT,SDOC. - Fix not to recognize escape sequences in TSTRING. - Fix to eliminate QSTRING which is not valid Swift literal syntax.
