Add extra ammo in bartender lockers

[IPingu]

The bartender on round start only has 8 bullets in his riot shotgun, the only way he reliably can get more is by hacking the booze-o-mat. So id think it would be very useful if the bartender would get extra ammo in his locker. Donut 3 bartender locker already contains an extra box of 12 ga rubber slugs and its very convenient, because I no longer have to hack the booze-o-mat.
