LUA Resol VBus module and example

[lpala]

I'm opening this new thread as I created (suggested by Edgars) a github repository.

The repository's URL (containing only the code and not LM example) is:
https://github.com/lucapalazzo/luavbus

It's my first github's repository, so please don't care about missing files, just report it here.

As always, feel free to ask, contribute, correct...
