[binary builders] luatex beta-0.85.0

Hi all, I have just pushed the beta-0.85.0 on the svn server. Please compile, test and report any problem. As usual, the new beta is "cold" but not "frozen", so we can still fixed something. It would be nice to have the binaries (at least) for osx, linux, windows and freebsd in the garden, so we will wait for them before the formal announcement. Hans, Taco, Luigi (in this order :-) )
