/* ----------------------------------------------------------------------------------------------
 * Name		: cs_join.c 
 * Author	: n00bie
 * Version	: v1.0.3
 * Date		: 11/08/2006
 * Update	: 29/09/2006
 * ----------------------------------------------------------------------------------------------
 * <Description>
 *		This module will make ChanServ JOIN / PART a channel & will automatically
 *		set correct modes for itself.
 *
 *		This module is designed for ppl who wanted to have @ChanServ sits on their
 *		channel along with a BotServ @Bots; and without the need of using ugly RAW commands for
 *		making ChanServ join a channel.
 *
 *		It is recommended not to use this module with cs_fantasy.c or
 *		cs_inhabitregistered.c loaded as those modules already does the job ;)
 *
 *		Also, when using this module i'd like to suggest the SYMBIOSIS mode turned off
 *		(if there is a bot assigned on a channel). See /BotServ HELP SET SYMBIOSIS for reasons.
 * </Description>
 *
 * NOTE: Only channel founder can use this command.
 * ----------------------------------------------------------------------------------------------
 * Providing Commands:
 *		/msg ChanServ JOIN #Channel
 *		/msg ChanServ PART #Channel
 *
 * Providing IRCD Handler for: KICK
 * ----------------------------------------------------------------------------------------------
 * Tested: UnrealIRCd 3.2.5 & Anope-1.7.13+above
 *
 * Change Log:
 * Ver1.0.0 - First public release
 * Ver1.0.2 - 1) Removed strtok();
 *            2) Fixed mem leak
 * Ver1.0.3 - Changed mode +oq to correct modes depending on the IRCd
 *
 * TODO   	: CS_JOIN_ALREADY
 * ----------------------------------------------------------------------------------------------
 * Thanks	: Tom65789 for his comments/suggestions ^^
 *            chaz for compiling the mod for windows users
