Cut-scenes and bugfixes

Version 2.4.1 is up with important changes and bugfixes:

• the new cut-scenes are added at the end of castle level and at the end of dungeon level
• the final room in the catacombs is added (after the boss fight)
• there were a couple of bugs regarding those cut-scenes which would make the game crash on some computers. These should now be fixed.
• the catacombs cut-scene does not play if you enter the catacombs via the forest shortcut
• the portal sound effects were too loud
• sometimes the game would get stuck during level transition, if the attack button was pressed during the fade-in and fade-to-black animations. This is now fixed.
• in co-op, a part of the portal graphics would disappear after the necromancer fight in the catacombs. This is now fixed and players who have completed the level are shown inside the portal until everyone enters
• returned goblins (instead of undead) to the blocked rooms in the forest
