fox for issue #38

[zbyhoo]

This fix makes possible to close wax with wax_end() and during same application runtime execute again wax_start().

Modifications:

1. stoping wax_gc during wax_end() by invalidating wax_gc timer
2. not throwing an error when objc class already exists
3. zeroing lua_State variable during wax_end()

One more thing. I had problems running my compiled version of the Framework project (error saying about bad header in precompiled stdlib file or something like that). The only solution I found was disabling compile-stdlib.sh script . By mistake I pushed that commit to my forked wax repository. I see that this commit was also included in pull request (but I send pull request earlier, I don't know github that much).

I don't know if it's big issue, but probably the project file should be reverted, it's up to you. I'm really sorry for the problem.

Besides that, do you know why this error occured while I was running my compiled version of the Framework project?
