Title: Store coordinate system in COORDSYS rather than COORD for compatibility with Fortran, IDL, C

healpy.write_map the stores the coordinate system in the header under COORD, but it appears that all of the implementations in HEALPix itself (at least in Fortran, IDL, and C) use COORDSYS. This patch has healpy.write_map use COORDSYS for compatibility.
