Fix Bug 671: Add JPEG Decoder w/o AWT Dependencies

Original JavaScript code from <https://github.com/notmasteryet/jpgjs/blob/master/jpg.js>,
author 'notmasteryet' <async.processingjs at yahoo.com>.

Ported to Java.

Enhancements:
 * InputStream instead of memory buffer
 * User provided memory handler
 * Fixed JPEG Component ID/Index mapping
 * Color space conversion (YCCK, CMYK -> RGB)
 * More error tolerant

+++

Features:
              JOGL   AWT
  RGB          ok     ok
  YCCK         ok     Exception
  CMYK         ok     Exception
  YUV Store    ok     n/a
  Need Y-Flip  no     yes
