Endless world

This new version (v0.0.2) contains the following changes:

• Now the world is infinite, this has been implemented by the use of chunks

• The world has also now biomes (ocean, plains, desert and mountain)

• World is much more bigger, moved from height 10 to 50 and the size generation  is double
  

• Fixed performance issues from before and the new ones that appeared with Chunks

With the addition of the chunks loading now the world is endless.

The biomes do not have any purpose yet except of being there for later.

For the next update I'll introduce the barebones of the Combat system. I'll write a blog about it with the detail
