Remove friendlySaving for now

Achievements are saved in the state field, so we don't have room to save
friendlies there anymore. DZE_FriendlySaving is removed for now. I will
add it back later with a save to player profile instead.

The dayz_players variable is not used for anything. There were several
other unused variables in server_playerLogin.sqf.
