Ah... you noticed that speed improvement, eh?? I thought I could sneak
that one in there without anyone noticing... ;-)

I changed two things:
* I stat all the .in files and there targets and only replace when the
  .in files are more recent (or if the Config.pm file is more
  recent). On a fresh install there are only the .in files, so
  everything is built, on an update only a few things..
* The old substitution code was quick to write, but slow to perform,
  loop over every .in file, loop over every line, loop over every
  subst param ==> !! n^3 !!. I changed it to be ~n^2 by only looping
  over the subst params *only if* there were any on the line. Since
  most files only have <1% of their lines substitutable, its an order
  of magnitude better.
