"module" is deprecated in Lua 5.2

I now you write mostly for 5.1 and the nginx stuff only supports 5.1. I've stopped using "module." I actually find the "create and return a table" method of doing Lua modules gives a little more control over what is exposed and allows the global environment to stay clean. I may do a fork using that method.

I've already removed module() from the code base :) Thanks!
