Changed Player's serialized(no interface change)

Stopped giving “Player” : before the object
Changed casts in Player

Casted object by object instead of array as a whole
Space loads correct subtype

In Cell, when loading a new space, it checks for which type it is and
then creates that type.
Serialize saves connected cells

Saves them as an array of objects holding the cells x and y
Connected cells (Load/Save)

Loading and saving connected cells by passing them in with the
JsonObject as part of the map. Accessed by getting the value for key
“list”
Less hardcoding, null checking

Check for null in connected cells, gets size of outsideInnerCells
instead of hardcoding 44.
Loading more robust

Checks if the json is initialized with “Game” or not and treats it
either way.
