Changeset 404 for trunk/game/objects

Patch by mvbarracuda:

• Restructuring the objects directory as discussed here: ​http://forums.parpg.net/index.php?topic=580.0
• Structure is surely not perfect at this point but getting rid of objects/objects is already a huge improvement over the status quo IMO; if there's the need for it, we can further restructure the directory layout later
