fix for DeprecationWarning: using a non-integer

Fixes these deprecation warnings from unitest in the TestShiftGrid class:
> test_cyc (__main__.TestShiftGrid) ... lib/mpl_toolkits/basemap/test.py:93: DeprecationWarning: using a non-integer number instead of an integer will result in an error in the future

This was done by changing the numpy arrays datatype from float to int.
