* Added hasMoved and isNew attributes to Tile type
* Made obsolete arbitrary content in previousPosition
* Made code more robust to creation of new tiles
* Made some changes for and against the original code
* Should have been aligned on the right, but had issues with the log()
function
* Best score is currently reset every time you launch the game
* Removed useless project files
* Each tile can only merge once per move
* Game update correctly after just moving
* Slowed down animation because it looked weird out of the emulator
* Fixed a single typo
Looks weird for merging animation, it's because one of the tiles isn't refered as its origin by the merged one, so it won't appears.
* Solution 1: Make a Grid with previous tiles of which animation is based with nextPosition instead
* Solution 2: Make two previousPosition. It does what the original one does, however less stable (affects every new tile definition)
