Renamed com.sun.opengl.utils to com.sun.opengl.util. Moved

TextureIO-related classes to com.sun.opengl.util.texture and
TextureProvider, TextureWriter and format-specific readers to
com.sun.opengl.util.texture.spi. Renamed BufferUtils to BufferUtil.
Added ImageUtil and FileUtil. Cleaned up javadoc. Updated demos.
Cleaned up some imports.
