JIU 0.10.0 released

The TIFF codec was updated to read 4-bit grayscale and paletted, CMYK and LogLuv color spaces, SGI LOG RLE, and LOG 24 Packed compression types. The Palm codec now reads and writes almost all possible format flavors. Spanish was added as a language in jiuawt. A wrapper class was added to use AWT BufferedImage objects directly in JIU operations. Some cleanups to make dithering and resampling more extensible were made, and ImageLoader now allows to add codecs at runtime. ImageCodec's new setFile method automatically picks suitable I/O objects, and an unsharp mask filter was added.
