Improve integration of int[], long[], float[], and double[] mathematically operations.

[Thrameos]

We have made excellent progress thus far in improving support for buffers and arrays. But we still can't do math operations on the Java side that would save the need for pulling the array across just to do some silly modification. Further with the ability to perform slicing, this is really needed to prevent generation of copies.

However there are some technical issues that remain. Having a partially functional reverse bridge would reduce the difficulty considerably. Thus this should be deferred to 0.9.
