New point version.

### Significant changes relative to 1.5.2:

1. Fixed a NullPointerException in the TurboJPEG Java wrapper that occurred when using the YUVImage constructor that creates an instance backed by separate image planes and allocates memory for the image planes.

2. Fixed an issue whereby the Java version of TJUnitTest would fail when testing BufferedImage encoding/decoding on big endian systems.

3. Fixed a segfault in djpeg that would occur if an output format other than PPM/PGM was selected along with the -crop option. The -crop option now works with the GIF and Targa formats as well (unfortunately, it cannot be made to work with the BMP and RLE formats due to the fact that those output engines write scanlines in bottom-up order.) djpeg will now exit gracefully if an output format other than PPM/PGM, GIF, or Targa is selected along with the -crop option.

4. Fixed an issue whereby jpeg_skip_scanlines() would segfault if color quantization was enabled.

5. TJBench (both C and Java versions) will now display usage information if any command-line argument is unrecognized. This prevents the program from silently gnoring typos.

6. Fixed an access violation in tjbench.exe (Windows) that occurred when the program was used to decompress an existing JPEG image.

7. Fixed an ArrayIndexOutOfBoundsException in the TJExample Java program that occurred when attempting to decompress a JPEG image that had been compressed with 4:1:1 chrominance subsampling.

8. Fixed an issue whereby, when using jpeg_skip_scanlines() to skip to the end of a single-scan (non-progressive) image, subsequent calls to jpeg_consume_input() would return JPEG_SUSPENDED rather than JPEG_REACHED_EOI.

9. jpeg_crop_scanlines() now works correctly when decompressing grayscale JPEG images that were compressed with a sampling factor other than 1 (for instance, with cjpeg -grayscale -sample 2x2).
