Split macglue.c into two: a new mactoolboxglue.c (in ./Python)
with functionality needed for both unix-Python and MacPython and a new smaller ./Mac/Python/macglue.c which contains MacPython stuff only. pymactoolbox.h has moved to ./Include from ./Mac/Include and now also contains the relevant stuff from macglue.h. The net effect of this is that the ./Mac subdirectory is not needed anymore for building the unix-Python core on MacOSX (it is needed for building the extension modules).
