Compatibility update for the new TrainCarts 1.14.4-v1 (Minecraft 1.14)

Changes

• Rail block position was not saved for junction nodes, it reset after server restart. This is now fixed.
• Global commands can now also be executed in the server console, not just by players.
• Fixed broken physics when nodes were really close together
• Fixed broken physics when nodes were close to a block's border (x/y/z = 0)
• Performance improvement by limiting the number of sub-nodes needed to represent a curve
• Selected nodes (sticks) now have the glowing effect, making them visible through walls
• Added configurable 'smoothness' factor, set using /tcc smoothness [value], stored persistently in config.yml
• Added api-version to the plugin.yml to silence a server warning
