Alpha 4 : When humans discover writing

The text is now essential to progress on this project.
To implement it I used a simple font manager class using textured bitmap font. There is a cool program to generate the metrics and the image, f2ibuilder

I added an Observer Pattern to allow some animations based on some events or instant items (like Laser).

The Laser animation uses a 3 parts image, to allow some long/short laser without scaling the texture. With this technique I can make it start as a short laser. After some few milliseconds, the size raises the maximum defined length and then reduces its size when it hits the target.
