New challenges ideas

[fiks]

Idea for new challenge:
Kill some zombies with turret
Kill some zombies with gl turret
Kill some zombies with coctail
Kill some zombies with pipe bomb
Get some hit from blue ball and dont die (wave 17)
Get some hit from pink ball (mixed and hitler wave)
Place some barrels
Place some collectors

And idea for skillpoints:
Put 25 skillpoints for open dont lost your weapon (like for golden gun).
Not like now, when must make Multi Talent challenge (too much skillpoint must use for this challenge).
