Refactoring

No big changes here related with code or content, but this is a refactor of classes and namespaces in order to decouple gwt.create presentation from the generic slides library. 

For the presentation you have to modify stuff under presentations/gwtcreate.

I have moved certain assets from the resources folder to the slides/public folder in the case of common stuff for other presentations, and others to the presentations/gwtcreate/public folder. 
I prefer this convention so as the gwt compiler copy assets instead of trusting in maven or IDE configurations.
