Create: Module Sub-Generator. Store User info in users dir under lib-config

I have been using your generator for a while, along with a sub generator I created. I finally had the time to make a pull request, and properly document it.

I also installed a few extra modules 
- gulp-storage: A Yeoman like config store, but for gulp. This stores config information in the users directory.
- gulp-finder: A Module that adds glob method to the templates directory.
- minimist: Arguments parser for the sub-generator.

I would Explain Everything else I did, but the majority is in the README. 
However, I tried to steer clear of modifying your slushfile, so that we did not have any merge conflicts, although I did add the task - module

If you have any questions, please let me know!
