Add badges in game sides for special wins

[antoinezanardi]

Some roles or groups must win by themselves to win the game. For each entity, a badge must be added in the respective side in order to tell the game master that game can be won by one of those entities. Those badges are in a section below the side name: The loners

• Pied Piper: Icon + percentage of charmed players. Disabled if pied piper is dead, infected or powerless.
• Lovers: Icon + percentage of dead players except them. Disabled if one of the lovers is dead or if cupid didn't choose them yet.
• White Werewolf: Icon + percentage of dead players except himself. Disabled if he is dead.
• Angel: Icon + pulsing trophy to indicate that he can still win. Disabled if day of turn 1 started.

Tooltips for each badge describe the objective of this entity.
