Oops: actually fix heap performance problem...

Performance fix for heap; correctness for _mcp
...
(1) normalize_indices in _mcp.pyx should convert indices to ints: fixed
(2) huge (order of magnitude) performance problems in heap.pyx from changing
lines like:
ii = (i-1)/2 # CalcPrevAbs
to:
ii = (int)(i-1)/2 # CalcPrevAbs
for some reason, the latter goes through the python division machinery!
However, the former is invalid for cython >=0.12, so the proper solution is:
ii = (i-1)//2 # CalcPrevAbs

Rewrite spath.shortest_path to use new mcp classes
...
spath.shortest_path presents the same interface, but now uses the new mcp
classes internally, which means that it is now fully n-d, and can also find
the shortest path along any given axis. The old output format has been
retained, but is a bit weird for non-2d arrays. A more sensible n-d output
format is available, but not enabled by default.

Added classes for minimum-cost-pathfinding through n-d arrays.
...
mcp.py presents the interface and a simple usage example; the classes of
interest are in _mcp.pyx. Basic tests are included.

Modify _build.py:cython() to be cleaner:
...
(1) Now uses subprocess.call instead of os.system, so that paths with spaces
(and the like) are handled properly.
(2) Removes superfluous .c.new files after deciding whether or not to copy
them to the .c files.
