Update to be more Laravel 4.x compatible

Hello,

I was in the market for a Laravel package to interact with the DreamHost API and found yours.  I ended up adding some flexibility to it, and thought you might consider accepting the changes.

- config file support
- Service Provider and Facade support added
- UUID function to enforce unique commands
- Lots of other stuff

What do you think?  I'm still working on updating the README.me.
