Vertical Gates
Adds a new Dev Tools object for vertical gates!
To make your gate vertical:
1. Add a file at `mod/modify/world/gates/vgates.txt`. In this file, add a line for each gate you want to make vertical, using to format `[ADD]GATE_XX_YY` (replace XX_YY with your gate’s acronyms).
2. The position of the gate is controlled by VerticalGatePosition in DevTools’ `Objects/Gameplay` section.
NOTE: For your vertical gate to display correctly, it must also be an electric gate. To do this, add the same `[ADD]GATE_XX_YY` line to `mod/modify/world/gates/egates.txt`.
