Nebula Extention + Adds back the Udang and Scoophead trade shuttles

[DeltaDav]

About The Pull Request

This is a simplier, and (I hope) workable version of my Last Nebula PR (closed Yesterday)
This also adds the new Area format asked by Silicon.

This aims to transform Nebula gas station into a proper space transit hub in the system, outside of NT, to opfully in the futur, give player the option to play someone not in NT, with enable spawns.

This doesn't replace anything currently on Nebula, only adds a part to the station. (IC wise : The under construction part). Its also plan to make the station a bit more lively (a bit.)

The idea is to have a more civilian part of Nebula, inspired a bit by Star Trek's DS9 station in its function (before it became the main landmark of the series) mainly a simple hub for refuelling and accommodating temporary travellers, or longer uncertain stuck people.

Imagine being playing a wannabe explorer, a corporation employee enjoying his retirement, or a simple cargo pilot.

This adds :
A Motel with 9 rooms
6 Shuttles low cost shuttle (Arrowhead, Teshari Runabout, Adventurer, Caravan, Tug, Micro)
2 extra trade shuttles (Udang for cargo/passenger, Scoophead for smaller traders) with pads and docks on Triumph and Atlas.

Comparated to the last PR :
Doesn't have vendors
Doesn't have new Ids.
