Bukkit

added spawn commands

/spawn -> teleports player to world's spawn point

/setspawn -> default permission only to OPerators, allows to set current world's spawn point where the player stands

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.
