[S] Simple Slattered/Mastercraft staircase add extra board on L-Shaped stairs

*snip*
There is a board on the landing of the stairs that could be tripping.

*snip*
I found a bug in the staircase structure.

*snip*
When you bend the stairs 90 degrees, a plank that could trip you appears.

*snip*
It doesn't affect whether the Sim can use it, but it's not good design.

*snip*
Please improve it.

Thank you.
