It seems that we have to use \ for paths on native Windows, and it
works on Unix as well, so just change all the paths accordingly.

The code to handle building in a separate directory had seriously
bitrotted. This contains a number of fixes to make it possible,
including bits like the documentation which never worked in the past.

Make the NSIS output automatically select the output architecture to
generate the proper filename and, much more importantly, set up the
proper default install directory.
This requires Perl as well as makensis to be present in order to make
an installer, but that doesn't really seem like a too onerous of a
requirement (NSIS being the big external dependency here.)
