Deeper into Blender file format

It appears that the DNA1 data block is the most important one. It is a sort of meta-block because it describes the structure of all other blocks.

I've successfully created a Java class generator that can write a Java class file from DNA1 information. I've worked only on the 32bits / little endian version of the format.

Using these classes (280+), I'm now able to decypher a Blender file.

The next step will consist of understanding the links between data blocks and the meaning of the data blocks of type DATA.
