By moving Config up to core (from FFI) we can take advantage of it from anywhere in the HAT code. 

At present we still only access it from FFI.  I plan to make more general changes in future. 

Also switched `java @hat/bld` to actually use the new `job.jar` based build (same for @hat/run ... sanity .. test clean etc) 

Have not removed the Script based tools. But will soon.  If you see a problem you can revert to the prev version using  `java @hat/obld ....` instead of `java @hat/bld ...`

There was an example with accesses to local memory specific to the CUDA programming model. This has been fixed and now it is compatible with both the OpenCL and CUDA backends of HAT. 

How to run?

When running Java multi-threaded applications with the HAT CUDA Backend we need to set the current context before building the kernel. This patch fixes this. 

Heal application should work now for the CUDA backend.

This will be a good demonstrator for recent  array view and local memory work. 

Also the basis for a reduction based violajones implementation. 

I also added matmul.iml so we can view matmul in intellij project

Here we leverage OpenCL's ability to lean on the C99 preprocessor to generate C99 code. 

Instead of having OpenCL generator differentiate, we get the OpenCL code builder to define a set of #defines and generate backend 'neutral' C99 code (common between Cuda and OpenCL). 

This PR just has the OpenCL changes.  Cuda changes will be next

Generated code essentially same for CUDA and OpenCL.  

Not only does this lend itself to simpler codegen, it also opens the doorway to a HAT C99 dialect which we can use for prototyping and even intrinsics

Check the code generated for 

HAT=SHOW_CODE java @hat/test ffi-opencl
HAT=SHOW_CODE java @hat/test ffi-cuda
``` 
The only differences should be the generated preprocessor macros.

We need to deal with atomics .... somehow. Still thinking about that.

Private and local arrayViews can now also be accessed using `.privateArrayView()` and `.localArrayView()`, respectively.

Implementation of `.privateArrayView()` and `.localArrayView()` is left to the user, and accessing global arrays is still kept as `.arrayView()`.
