Added:
* /aa_mutecommand can now mute sub-commands
Example: /aa_mutecommand "say ahoj" -> this will mute "/say ahoj" but will not mute "say hello" or any other parameter to the /say command
IMPORTANT: this functionality is greedy by default, meaning that muting "say hello" will also mute "say hello mum", "say hello dolly"
and anything else that follows the "say hello" command. This is to accommodate commands with player names, world names, etc. as parameters.
For example doing '/aa_mutecommand "minigame kick"' and executing "/minigame kick player1" may prevent displaying
message about a kicked-out abusive player from game for everyone in the game and help players concentrate
on the game itself.
