Issue description:
Elevators on 12 floors. All 12 buttons show on the screen, but when in two columns, the columns are the wrong way around.

This is what is displayed:

5 1
6 2
7 3
8 4
9
10
11
12

Should be like this:

1 9
2 10
3 11
4 12
5
6
7
8

Steps to reproduce:
Setup elevators on more than 8 floors so that the buttons display in two columns.

Versions:

• Minecraft: 1.12.2
• Forge: 14.23.5.2847
• CompatLayer (only if on Minecraft 1.10 or 1.11):
• McJtyLib: 1.12-3.5.4
• RFTools: 1.12-7.72
• OptiFine: 1.12.2 HD_U_F4_pre3

Closed it because this was for descending floors where 1 is ground level and 12 is bedrock. Power obviously is on 12, so that kinda makes sense.

Would be nice to be able to toggle it the other way around though.
