    A few functions to make it easier to include files and folders
    Thanks to TheMaw for this idea, this entire file is basically ripped form GearFox.

    You can AddLua(SV|SH|CS)Folder(foldername) to add that folder in the domain.
    Additionally, in the shared domain, if a folder has the folders sv_*.lua and cl_*.lua, and optionally sh_*.lua, these will be included in the server, client, and shared domain respectively.
