[Context] Luatex 0.47.0

Dear builders, the new LuaTeX beta-0.47.0 is not compatible with beta-0.46.0, so it's important to commit the new version of luatex as soon as possible. Please check if ./do_all.sh does the job (apart from compilation problem of pdftex on FreeBSD). Hans - since it seems to be working now - feel free to do svn up and then uncomment "--without-trunk" in do_all.sh and add the script to cron job on the server. Thanks to everyone, Mojca
