Travel anchors

Adds a travel anchor block for easy home/base navigation

After crafting, you can use travel anchors in two ways:

1. As elevators: just place one the above other and use jump/crouch to travel up and down. You can make as many as you want. 
2. As a real game changer for big homes: place 2 or more anchors, open their UI (default by F) and set their names. After that, you can teleport to any of them from the anchor UI

If you are a server owner, you can change the [maximumDistance] value in config (mods/deos_TravelAnchors/TravelAnchors.json) to change how far you can travel between two named anchors
