Limit /dropweapon pickups between cops and civilians.

So some guys say this is teaming with cops and it's against rules and keep reporting players. Some says no itsnt and keep doing /dropweapon.
Well this caused me to be infracted although itsnt available in /rules

The solution is that cops cant pickup weapons thrown by civlians and vice versa. This would be great instead of punishing players who cant find this rule in /rule
Non-cops will no longer be able to pick up weapons dropped by cops, as cops get a discount. I haven't made it like that vice-versa though - a cop can pick up weapons dropped by civilians.
