Implemented the character rotation without the Scatter widget. It will allow to use the character with the stencils, since it's canvas only now.
Other players are now visible, their position and direction is updated. If no info is send, the sprite will be hidden. #15
Implemented collisions for Players displacements. Issues #6. Need to be tested.
Fixed a bug (typo...) in map_parser.py + added two attributes. + added bounds checks when checking for collision in the GameEngine
Added two tests for the collisions when moving + fixed the speeds in the others tests. Issue #6
renamed x and y to row and col in the map parser to make it more explicit that they are not pixel coordinates
Added support for extra information in the map format.
Used it to add the camera orientation
