From 55eba91c566d566b07fccb782ca35e0a829619d5 Mon Sep 17 00:00:00 2001
From: Oliver Tappe
Date: Sat, 9 Feb 2008 20:17:10 +0000
Subject: * dropped attribute ramfs_screen as it is no longer needed (splashy
 does   not need to be given the screen-size) - updating schema version to
 0.25 * little code simplification in DBSchema.pm * removed ramfs_screen from
 all tests * added method removeAttributeByName() to MetaDB in order to be
 able to   remove attributes from the DB in a simple manner
