New Craftable Item: Ladder

[Hirnsausen]

This is a suggestion

 

Another good option would be to have a regular ladder, good for inside ships and bases. Such a regular ladder would consist of a 2 voxel wide item that is also just 2 voxels high. It is the combination of several of them that makes a ladder - ideal because then the players can create that way ladders of different required heights, fitting the height of their floors.
