A few minor Java wrapper changes

[nneonneo]

Here's a few minor Java changes, for happier development.

• Implement every API in fakenect, which resolves linking errors that can occur when using Java with fakenect.
• Bump the version number of the JAR
• Add a Makefile for the JAR (mostly since I never remember the right mvn command to use)
• Build a JAR with dependencies by default, which makes it slightly less painful to deploy
• Like the other wrappers, don't set a default depth or video mode (the default modes that libfreenect sets are fine).
• Order the data buffers correctly (according to native byte order instead of the default BIG_ENDIAN), so that you can make ShortBuffers from them that work properly
