#7 fixes for -DNPY_NO_DEPRECATED_API=NPY_1_7_API_VERSION

[Jack Howarth]

When compiling pymol 1.7.4.0 against numpy 1.9.1 with -DNPY_NO_DEPRECATED_API=NPY_1_7_API_VERSION passed on CFLAGS, the compilation fails on several files due to missing casts of (PyArrayObject ) or (const PyArrayObject ). The attach patch eliminates these compile errors.

Note that setup.py should either append -DNPY_NO_DEPRECATED_API=NPY_1_7_API_VERSION to CFLAGS or

#define NPY_NO_DEPRECATED_API NPY_API_VERSION

should be added to the effected files (layer0/Field.cpp, layer2/CoordSet.cpp and layer3/Selector.cpp) to avoid the warnings...

/sw/lib/python2.7/site-packages/numpy/core/include/numpy/npy_1_7_deprecated_api.h:15:2: warning: "Using deprecated NumPy API, disable it by " "#defining NPY_NO_DEPRECATED_API NPY_1_7_API_VERSION" [-W#warnings]
#warning "Using deprecated NumPy API, disable it by " \
 ^

Passing the -DNPY_NO_DEPRECATED_API=NPY_1_7_API_VERSION across all of the files in pymol might be wiser since it will capture any future code additions which tickle this ABI issue.
