From bc27fd19cb14a7df848fe679adf5cef94e1e6bb2 Mon Sep 17 00:00:00 2001
From: rakshasa <sundell.software@gmail.com>
Date: Tue, 21 Jun 2005 16:23:34 +0000
Subject: [PATCH] Cleaned up option_handler_rules.*, it now uses the slot_map_*
 properly.

Erases the screen upon quit.

Added option for checking the hash for completed downloads.
