BETA: Implementing retail-like clan leader changes:

	* Note: In retail clan leader change requests are applied during maintenance here we'll schedule this to Tuesday (Or any other day you set in config).
	* Instant clan leader changes are still possible but disabled by default.
	* You can apply pending clan leader changes before Tuesday via admin command: '''!//clan_show_pending''' .
	
	* Reviewed by: Zoey76, Tryskell
	* Requires: [DP9492]
