Update mapping.md - Atmos, telecoms, beacons + (#193)

Adds new atmos stuff:
- Air Alarm
- Fire Alarm
- Air Sensor
- Gas Recycler
- Gas Condenser

----
- Adds mention for the telecoms server.
- Reformatted the warp points section so it starts with station beacons
as the preferred method with warp points as an exceptional circumstance.
- Some more minor edits like putting some commands in code snippets,
added a hint, removed some bloat.
- Adds a tiny heading for escape pod mapping.


Mapping wiki is in a sorry state of maintenace so since I wrote the
majority of it in the first place thought I'd come back and start to fix
it.

 To assign an entity to a slot, you can just open the entity placement window and click on an entity to start placing it. Clicking on an empty toolbar slot instead of somewhere in the game world will save that entity to that slot. If you are currently in the entity-eraser mode, clicking on an empty slot will instead create a shortcut to the erase-mode. You can assign tile-placement actions in a similar way. Note that tile deletion is simply the same as placing down space-tiles. Finally, to assign decal actions you need to open the decal menu and configure your decal selection. Once again, clicking on an empty slot will add that decal to the toolbar. You can't save a decal-erasing shortcut to the toolbar, as this requires the decal placement window to be open. To remove an action from a slot, simply right click that slot (assuming the action toolbar has not been locked/frozen).
 
-A preset collection of mapping actions can be loaded to the toolbar by using the loadmapacts command. Note that as actions are unique to the currently controlled entity, if you use ghost or possession commands you will lose these actions and will have to re-run the command.

 ## Multi-Grid and Multi-Station Maps
 A station and a grid are not the same thing. For example, each asteroid is not it's own station, while a station may consist of multiple grids (e.g. escape shuttles). Most maps only have one grid, though you do still have to set up stations regardless. However, since you can use savemap and loadmap to save/load maps with multiple grids, there is support for overriding this behaviour.

+* **Air Alarm** - Used with Air Sensors in order to detect harmful atmospheric conditions on areas and feed alerts to Engineering / Atmospherics. Use machine linking to connect air sensors in **adjacent** rooms to the air alarm, as well as vents and scrubbers in the **current room** to the air alarm. Also connect the firelocks between rooms to the air alarm so that it can trigger them to block off sections.
