0.6.2: beware, lava!

Hot lava!

You can now add lava pools, exactly the same way as water pools.

"Small furniture" object

A single small square object that can represent whatever you have in mind.

New icons

I started re-working the placeholder icons, starting with save/load & a few others.

The Graveyard

Added a new example map

Minor things:

• Fixed water pools + diagonals walls render.
• Fixed water leaking through thin walls.
• Fixed many minor rendering issues with water pools.
