New levels, performance boosts and map polish.

After much discussion, I've decided to focus on Pets before Loot. Pets will be stat-boosting and upgradable. How they unlock, how they work has still to be decided, but a hard evening's work and it's already looking kinda neat.

On top of that, we're mostly happy with the initial raft of maps available, so I've extended it to cover 2 bosses and 3 dungeons across 12 levels. I spent about 6 hours playing the maps and making tweaks based on that today, so I'm happy to push this patch out now.

• Auto detail should now smartly modulate Ambient Occlusion based on resolution.
  
• Low Detail will now force you to 1280x720p, if you're in a regular 16:9 base resolution.
  
• Another raft of polish across all current levels.
  
• Unlocked access to level 12, allowing players access to 2 dungeons and 3 bosses.
  
• Fixed an issue where choosing a new difficulty didn't update the accessible ring on the map.
  
• Added different ways for Map Designers to spawn Gnomes into the map, to add to the variety. AutoGnomes should also have a significantly different look, so players shouldn't try and resurrect them.
  
• Fixed super-high pitched pickup SFX
  
• Started work on stat-boosting combat pets.
