bug: all doors have a lighting bug

[JossDarkwood]

Every door (except for the palm door, for some reason) has a bug where, when opened, the front face of the door is extremely dark. It only seems to happen when there's a solid block on the side opposite the hinges (ex: if the door opens to the right, then if there's a block to the left, the bug happens.) I know Minecraft's lighting system is a little broken, and I think I've seen this exact thing with vanilla doors in the past, but I figured I should post about it in case it's something you can fix.

Also, none of the palm wood blocks have a crafting recipe (except for the basket and the hanging sign). This is probably intentional, they probably just haven't been added yet, but I thought it was something worth mentioning.
