Refactor GameStates

[Aevyz]

Merge this after everyone else has finished their end term merges, it's not that pressing.

Why

Games have entry conditions, you can only play them if ROS is enabled (Snapchat) or if the Internet is enabled (Akinator). Future games are likely to also have similar limitations. ChooseGameState must be able to handle this.

What was done

Games now shall extend an abstract class GameState. This is so that we can record the entry conditions, error messages and tags in each class, rather then alter ChooseGameState massively. Hopefully fulfills OO principles a bit better.

Furthermore, only games that can be played shall be suggested and the game shall be checked once again before entering the state.

Stuff Offloaded to GameStates

• Tags
• Start conditions
• Message if cannot start
• Transition Name
• Stop checking (code was copy pasted 2x)

Extras

Additionally, some other features were implemented as a byproduct of this PR

• NetworkUtils that pings 3 different servers to check if the internet is working
• Map now has two new methods, to "recreate" a bidirectional map
• Akinator has been fixed to not crash program in no internet connection on startup
• Improved Logging

Todo

• Document changes
• Test to isolate all bugs
• Improve HashMap creation process, some of it is pretty hacky
• Write Unit Tests
