Robot Army v0.1.3

Robot Army v0.1.3
Concept:
Manufacture and deploy automated soldiers to go out in hunting parties to annihilate the biter menage, or an opposing player's base/army.

How it works:
A manufacturable "droid" soldier unit which is placed like any normal object or deployed at the Droid Assembler. They move around and can form squads and attack nearest biter bases. They have a red tinted player sprite and machine-gun style attack method. Wherever you choose to place them, the soldiers mingle around until there is a minimum squad size, at which point they will move to go hunt. They can be placed at any time during battle if you want some backup while taking down a huge biter nest. Be aware . They engage with the enemy and will aggressively hunt nearby biters/nests. They may slaughter their way through an entire (early to mid-game) biter nest or at least die trying. Huge numbers will be needed to take on biter nests with large worms and medium/large biters. The mod will be expanded to add more powerful and different types of robot soldiers in order to help deal with that issue.

Changes from 0.1.2 to 0.1.3:
-added Droid Assembler building and icon for it
-added intermediate droid item which is placeable by player or inserted into Droid Assembler to produce a "deployed" Droid which is spawned nearby.
-Droid Assembler spawns finished deployed droids to the RIGHT HAND SIDE of the building (this is just how it's coded for now. I'll do building-rotation based spawning location later)
-Droids gather into squads of 5 (default, changeable in config.lua) and then hunt for enemies. enemies within 5000 tiles, biter and/or enemy player forces.
-Droids auto-join nearby squads (configurable range config.lua) or create their own new squad if nobody nearby
-Droid's animations and selection box etc were fixed, much better now.
-Recipe adjusted to use basic armour not heavy armour - this has reduced the cost in steel significantly.
-Reduces Droid's resistances to be more in-line with their downgraded armour.
