• Go through the current version of the Tiled parsing library and see what could be improved.
• Ensure that most attributes and information is obtainable through the library.
• Improve the documentation.

• Change the namespace that is being used to wanderer instead of albinjohansson::wanderer.

• Change all components that use the old style of having private members at the top of classes.
• Make sure that non-static members feature m_ prefix.

• Support loading multiple tilemaps at startup.
• Make it possible to change the active world from within the game. Minimum: be able to approach a door and "interact" with it in order to switch level.

@all-contributors please add @oscaralmstrom for review and ideas

• Look into reducing the excessive amount of classes in the hierarchy.

The flickering is presumably caused by the floating-point accuracy rendering and might be addressed by removing any potential casts to int, etc.
