[binary builders] New LuaTeX and MetaPost

Hi, Taco announced the release of new LuaTeX and MetaPost a few hours ago. This means a new request for building for you, however in the experiments so far LuaTeX only compiled on two out of three platforms for me (it failed on i386-linux and sparc-solaris) and there seem to be some more generic problems with metapost (missing file for inclusion), so please don't be surprised if you experience problems (or rather: please be patient until potential problems get resolved, and report problems if you experience any). Norbert also found a compatibility problem (older ConTeXt doesn't run with this LuaTeX). Merry Christmas to everyone, Mojca
