don't spawn Tux in the ground

[ghost]

When returning to the main screen from a world, this warning would appear:

[WARNING] src/supertux/sector.cpp:231 [levels/misc/menu.stl] Tried spawning Tux in solid matter. Compensating.

Since Tux is always "small" in this level, this code is triggered, which pushes Tux into the ground. By moving the spawnpoint up to match other levels, it pushes Tux to the expected position.

supertux/src/supertux/sector.cpp

Lines 222 to 223 in 40d1fac

	if (!player.is_big()) {
	player.move(player_pos + Vector(0,32));

I'm not sure I understand - how does moving the player to the right fix a vertical-based bug?

EDIT: I retract my comment, I saw the explanation in the linked issue.

So this PR closes #240?

No, it only fixes one instance of this.
