Lands of Elderlore 0.0.7

This release is not playable yet, but can be of some interest for someone wanting to code an outdoor world.

This release have the following new features :

* a new area system : from each world cell, an area of 32 x 32 cells is built. So with a standard 65 x 65 world, you'll get a 2080 x 2080 playing field.
* a new exploring system : once you've crossed an area, the relative world cell becomes known and you can travel on it on the World view.
* mouse movements : you can move around by clicking with the mouse, or even better by rolling your mouse wheel.
* a new graphical theme I borrowing from the creator of the GUI I am using, OcempGui
* A messaging system
