    wxluafreeze.exe currently doesn't handle precompiled
    (to bytecode) Lua files. Below we precompile the files
    and then convert them to an escaped string inlined
    in a small bootstrap lua script. Unfortunately, such a
    form is slightly bigger (!) than the original lua
    script (including comments!). However, that leaves me
    in doubt as to whether wxluafreeze can handle all
    Lua-allowed strings properly, so I prefer to pass them
    through the encryptor anyway.
