Online PiL 1st Ed. Errata

["Stuart P. Bentley" <stuart@...>]

?Before the 5.0 oriented code on http://www.lua.org/pil/24.1.html, it notes 
that "WARNING: this code is for Lua 5.0. To run it in Lua 5.1, you must 
change the five calls luaopen_*(L) to a single call to luaL_openlibs(L)."

However, it neglects to mention that also in 5.1 lua_open() should be 
changed to luaL_newstate().
