Add option to the EmailIgnore model to allow emails from an ignored address to be deleted (previous behaviour was to keep them all, so the mailbox could potentially become quite large - and every message was downloaded again every time the mailbox was checked). Upgrade instructions provided to both add the new database field and automatically switch to the old behaviour.

+A new flag was added to the 'IgnoreEmail' model to allow emails from ignored
+addresses to be either kept in the mailbox (for manual checking) or deleted.
+
+A new column called 'keep_in_mailbox' (type boolean, not required) is to be 
+added to the 'helpdesk_ignoreemail' table. The 'UPDATE' command will set all 
+ignore list entries to 'Keep mail from ignored address', which is the previous
+behaviour.
+
+    ALTER TABLE helpdesk_ignoreemail ADD "keep_in_mailbox" boolean;
+    UPDATE helpdesk_ignoreemail SET keep_in_mailbox='t';
