Adds a series of useful functions used by Bob's Mods. These can easilly be used by other mods too.
Lua libraries for use by other mods and submods that are parts of a larger mod.
For some reason gate textures don't work properly with purple/re-inforced walls. The door shows but underneath the lights, there's nothing attaching to walls.
This will be fixed in the next version. https://github.com/modded-factorio/bobsmods/issues/130
