Bukkit

finished freeze, kick and mute commands:

/mute <Player> [time] -> mutes a player indefinitelly or for a given time period

/unmute <Player> -> unmutes a player

/freeze <Player> -> freezes or unfreezes a player

/kick <Player> [reason] -> kicks given player from the server, optionally providing a custom reason

Regexs do not always execute in the right order, so, for example, a chat message containing the "MF-word" will be caught, instead, by the "F-word" replacement, despite the "F-word" regex being placed after the "MF-word" regex in the chat replacement list.
