Refacturing, cleaning and completeness

This release is the first non pre-release. I consider the central basic core parts ready. A lot of refacturing has been done to make the structure of the source code cleaner and with looser couplings.

Further development will circle around improveing the basic core parts, without major changes. While new features will be built on top of the core parts.

For documentation I will focus on tutorials, for others to now how to built apps open the liquid base.
