Adds watchtowers

Construction:

1. Make 2x2 of dislodged girders
2. Welder the bottom left dislodged girder
3. 60 metal rods
4. Blowtorch, Wrench
5. Screwdriver + 50 metal in offhand
6. Crowbar + 25 plasteel in offhand
7. Wrench + 60 metal rods in offhand
8. Blowtorch + 25 plasteel in offhand

Hitboxes:
Orange - Removed in later commit, ignore
Red - Always blocks movement (two 2x1s)
Green - Allows movement if you are ontop of the watchtower (1x2, this is where you after climbing into the watchtower)

Mechanics:

1. Only marines and non-big xenomorphs can climb the watchtower, from the tile infront of the ladder
2. Being ontop of the tower gives you 2 extra tiles of view and makes your shots arc so they only hit what you click, skipping all other mobs
3. Xenos can damage the tower by slashing it
4. Marines can repair the tower by patching it with a welder and metal in offhand
5. The tower does not protect you from most xeno abilities

Explain why it's good for the game

Besides the fact it's cool I cannot tell if it is actually good for the game without some testing and adjusting

Testing Photographs and Procedure

Some videos are from different commits so they might be outdated but they show the general concept
