New map: Frontier

[RedRafe]

Added a new scenario based off the mod Frontier Extended

[RedRafe]

Yes, code is just an adaptation of the mod's code to make it a scenario. I'd also prefer to port some functions to our modules style.

I'd say dont merge rn, it's currently being tested on S19, let's see if fixes and other features are needed and I'll tidy things up before actual merge.

Changes

• [x] refactored all the code and simplified it a lot (50% of original file with same features supported, most important: move_silo now uses the LuaEntity::clone API instead of calculating all the different cases...)
• [x] moved DO:Expanse's price_raffle.lua to common resources since they now both use it
• [x] added loot chests when destroying biter nests
• [x] localised player messages
• [x] moved variables from global to our Global system

  Note: I've moved many variables inside the new global data table instead of leaving them locally in the file, that's intentional as I'd like to implement a restart/GUI system to manage these variables when restarting/resetting the map to tweak the diffuclty/landscape

• [x] added new map description
• [x] added scenario template for frontier

I think this would be a good moment to merge (after review), as I plan to add GUI/soft-reset features to this map and I know I'll be changing a lot of code around in other modules as well and I fear it'll get too big to manage in 1 PR alone :) map is being playtested currently ans will be updated via our webinterface to add the new loot feature next restart.

Edit: saw now, will move price raffle to other dir ;)
