Changed binary format for 3.1.05.

Browse Source 
* String encoding simplified for reading by using number of bytes rather than number of UTF-8 characters.
* Parent bone index is no longer minus 1 and omitted for root.
* Mesh and weighted mesh vertices array is no longer preceeded by a length. UVs array length is vertex count, not vertex array length. Edges changed to short.
* Bounding box vertices array length is vertex count, not vertex array length.
