Build 0.00.4

I worked a bit, figured why the repair script didn't work, I am a dummy , I wrote " if(repair_cost>=resources_available) repair();" while It should be the opposite.

So:

Repair system works.

---

Added 4 more recipes in the crafting menu:

-DP-27 and ammo ( machine-gun)

-Lahti Rifle and ammo ( WWII anti-tank rifle)

--

Added a refitting window accessible through the repair one allowing the player to change the main weapon on his car.

---

Kept the forced spawn for enemies when pressing Z.

---

New build will add more random encounters and maybe a city.
