+ * myconfig_ignore = ignorelist_create (YourKnownIgnore);

+ * Append single entries in your cf_register'ed callback function:
+ * ignorelist_add (myconfig_ignore, newentry);
+ * When you hit the IgnoreSelected config option,
+ * offer it to the list:
+ * ignorelist_ignore (myconfig_ignore, instantly_got_value_of_ignore);
+ * That is all for the ignorelist initialization.
+ * Later during read and write (plugin's registered functions) get
