From 47d7b87570ce3c79d3e0a6b8e765c74d065b6ba5 Mon Sep 17 00:00:00 2001
From: Christian Heller <c.heller@plomlompom.de>
Date: Thu, 27 Jun 2013 03:07:53 +0200
Subject: [PATCH] Sorted out library dependencies / includes. Include every
 header file needed by each file individually, don't assume any inherited
 includes. Use forward declarations where possible.
