+/* This file contains all the functions used for the ban center.
+
+	void Ban()
+		- the main entrance point for all ban center functions.
+		- is accesssed by ?action=admin;area=ban.
+		- choses a function based on the 'sa' parameter.
+		- defaults to BanList().
+		- requires the ban_members permission.
+		- initializes the admin tabs.
+		- load the ManageBans template.
+
+	void BanList()
+		- shows a list of bans currently set.
+		- is accesssed by ?action=admin;area=ban;sa=list.
+		- uses the main ManageBans template.
+		- removes expired bans.
+		- allows sorting on different criteria.
+		- also handles removal of selected ban items.
+
+	void BanEdit()
+		- the screen for adding new bans and modifying existing ones.
+		- adding new bans:
+			- is accesssed by ?action=admin;area=ban;sa=add.
+			- uses the ban_edit sub template of the ManageBans template.
+		- modifying existing bans:
+			- is accesssed by ?action=admin;area=ban;sa=edit;bg=x
+			- uses the ban_edit sub template of the ManageBans template.
+			- shows a list of ban triggers for the specified ban.
+		- handles submitted forms that add, modify or remove ban triggers.
+
+	void BanEditTrigger()
+		- the screen for adding new ban triggers or modifying existing ones.
+		- adding new ban triggers:
+			- is accessed by ?action=admin;area=ban;sa=edittrigger;bg=x
+			- uses the ban_edit_trigger sub template of ManageBans.
+		- editing existing ban triggers:
+			- is accessed by ?action=admin;area=ban;sa=edittrigger;bg=x;bi=y
+			- uses the ban_edit_trigger sub template of ManageBans.
+
+	void BanBrowseTriggers()
+		- screen for showing the banned enities
+		- is accessed by ?action=admin;area=ban;sa=browse
+		- uses the browse_triggers sub template of the ManageBans template.
+		- uses sub-tabs for browsing by IP, hostname, email or username.
+
+	array BanLog()
+		- show a list of logged access attempts by banned users.
+		- is accessed by ?action=admin;area=ban;sa=log.
+		- allows sorting of several columns.
+		- also handles deletion of (a selection of) log entries.
+
+	string range2ip(array $low, array $high)
+		- reverse function of ip2range().
+		- converts a given array of IP numbers to a single string
+		- range2ip(array(10, 10, 10, 0), array(10, 10, 20, 255)) returns
+		   '10.10.10-20.*
+
+	array checkExistingTriggerIP(array $ip_array, string $fullip)
+		- checks whether a given IP range already exists in the trigger list.
+		- if yes, it returns an error message. Otherwise, it returns
+		  an array optimized for the database.
+
+	void updateBanMembers()
+		- updates the members table to match the new bans.
+		- is_activated >= 10: a member is banned.
