Loading stage from file

[mangelin]

In order to simplify the creation of levels, we want to write e loader that are able to load a level from file and instancete all the scenes that compose the stage. The level file will use the json format. Each row is composed by a maximum of 10 block

Blocks:

• 0: empty block
• 1: green block
• 2: red block
• 3: yellow block
• 4: blue block

{ "name" : "Level Name", "rows" : [ {"block": "green": "texture": "path"} ] }

every item in of the row is a dictionary with the property of the node. This could be useful for further extensions. For now the basic properties that we need, should be:

• block (type of block, empty special block)
• texture (path to the block texture)
• energy (integer that represent the block resistance)
