Improve the scijava.natives properties

We now define four platform family names: short, medium, long, longest.
And we define a property scijava.natives.bits for bitness.
If what you need is os.arch, you can reference ${os.arch} directly.

The scijava.natives.classifier property is now defined as
${scijava.natives.family.medium}_${scijava.natives.bits},
resulting in the following values for our five favorite platforms:

  windows_32, windows_64, osx_64, linux_32, linux_64

If you need something else for your particular platform-specific
classifier, you can define your own property. Examples:

  <lwjgl.natives.classifier>natives-${scijava.natives.family.long}</lwjgl.natives.classifier>
  <ffmpeg.natives.classifier>${scijava.natives.family.longest}-${os.arch}</ffmpeg.natives.classifier>

And then in the dependency, reference the corresponding property.
