Add taunt commands

[tdauth]

• "-mockson/-mocksoff": Disabling mocks disables sounds.
• "-mock X Y": X is the mock number or ID, Y is optional a player number or multiple player numbers.
• "-mocks": Lists all mocks.

Mocks are sounds and messages like in AoE2.

Cooldowns per player to avoid spamming.
