Changes 4.1:
* New or improved syntax files for the following languages:
        * Groovy, R, Clojure, Rust, Coffeescript, Java, Scala, Swift, D,
          AVR, Ruby, Perl
* New translations
        * Chinese (zh_TW)
* UTF-16 support
        * JOE can now edit UTF-16BE and UTF-16LE files.  It does this
          by converting them to UTF-8 during load and back to UTF-16 during
          save.
        * Within JOE, native byte order is called UTF-16 and reversed order
          is called UTF-16R.
        * If you change the encoding (with ^T E) between UTF-8, UTF-16 and UTF-16R,
          JOE will convert the file to the desired encoding on save.
* New regular expression engine
* Unicode improvements
* Code clean up
* Bugs fixed
* Minor enhancements
* jmacs fixes:
* ESC g (grep/find) and ESC c (compile) improvements
