Rails of War

This release is a general port of the old features to 1.12.2, featuring the narrow gauge tracks and some rolling stock.
- All track were made parametric, which provides more freedom in track building.

- Instead of old pre-set track items, track tools were added which allow you to place tracks of desired shape and (practically) any size.

- Track tools will show the trace of the future track, to make track composing even more easier.

- When placing tracks, special markers will indicate obstacles or faulty bed if so happens.

- New track shapes were added: wye switch, and three types of diamond crossing.

- Slope is now smooth rather then wedge and is placed with straight track tool by using mouse wheel.

Since the gauge was switched to narrow (750 mm | 2'5 1/2" | 12 texels), whole new set of rolling stock was added:

- Kof locomotive,

- Passenger carriage,

- Flatbed,

- Skeleton car (spinecar),

- Minecart.

New coupling system was implemented: activate coupling mode for each car using prybar, then push them together until they couple.
Right now stock isn't very functional, since the main focus is set on tracks. Cars coupled in trains can also behave jiggly and rubberband occasionally. That will be entirely reworked when the tracks are done.
