Some minor fixes

Fixed detfield count on list page.

Healed wounds from doctor bags are now random, and a doctor bag will
heal more wounds if the action is performed by another player to
encourage teamwork.

Fixed an issue with admin commands since the new level was added.

Fixed a crash bug with wound infliction reaching the limit in
SetPlayerWoundData.
Added ammo tin ammo transfer code

Ammo can now be transfered from an item on the ground (ammo tin or
weapon) to a held ammo tin.
