Day 2 features and improvements

Adding some improvements based on the live demo we had last week:

- 2 weapon spawners added spawning weapons on a 10 sec intervals 

- 2 health pack spawners in the middle of the map

- Also removed the debug "Shift+D" for spawning random weapons

Hopefully this will assist the players in finding a weapon when they "accidentally" throw away their starting one :D

Enjoy and feel free to comment on the standing issues. This will certainly help me to focus and prioritise development better!
