New Blocks, HUD

Whats new in this version of game:

1. New textures. Looks better then old ones.
2. New blocks. Grass, bricks, wood, leaves, and gray block.
3. HUD. Player now can select what block he wants to create.
4. Limitations. Player can build and destroy block which are near him, and he cannot create block in player position.
