From 651d22b873754cf4907a67f0f3c7e18eafdd7636 Mon Sep 17 00:00:00 2001
From: Max Horn
Date: Sat, 16 Sep 2006 19:31:23 +0000
Subject: * Added virtual Engine::getDebugger() method * Removed code from
 errorString() methods that hooked the debugger(s)   into error(), in favor of
 using getDebugger() from within error() * As a consequence, removed most
 custom errorString() methods
