Added code to compute clover field.
Interface is rudimentary and the code needs proper testing.
Will almost certainly change in the next 24 hours.

    Added code to compute the clover field.
    The backend code is in lib/clover_quda.cu. I have included a rudimentary interface, but
    this will almost certainly change in the next 24 hours. The code compiles, but
    needs proper testing.
