CudaClaw : Add user member to clawpatch; store allocated pointers to fp, fm, gp, gm for re-use #139

  1. Add a void* pointer in the clawpatch class;
  2. Create virtual user access function so this can be set by solvers
  3. Use this void star field to store pointers to memory allocated on the GPU for fp, fm, gp, gm.

This should cut down considerably on time spent in GPU access.

User data is stored in the patch object. Might be reasonable to move this to clawpatch, or to create a "cudapatch".
