Made lua_ member in config.d a static member. Created member pattern_ in todofilereader.d.
Added static default constructor to LuaConfig.
Added new slash commands made available in dmd 2.066.
Added support for new argument parsing code.

This new code still uses docopt but adds a layer that makes it less ugly and somewhat simpler.
Added base class for luastate.

This allows LuaAddon and LuaConfig to share the same LuaState.
