Moved the serverless game stuff out of msoy and back into the vilya library.
We'll be using this in game gardens, at least. Note that the actionscript side currently doesn't compile because of limitations in building a .swc file, but that'll be fixed soon. git-svn-id: svn+ssh://src.earth.threerings.net/vilya/trunk@47 c613c5cb-e716-0410-b11b-feb51c14d237
