[wxlua-users] wxLua now uses an unmodified copy of lua 5.1.1

[John L. <jla...@gm...>]

I have rewritten the coroutine code so that we do not have to replace
luaE_newthread and luaE_freethread by pushing the wxLuaStateRefData
into the registry table.

Hopefully this will make using wxLua as a lua module using require
much easier... of course the build files have to sorted out.
