Small timer fixes. Added cvar zr_roundend_balance_teams. See details.

Added cvar for disabling team balancing on round end (for use with custom team balancer): zr_roundend_balance_teams. Disabling this will cause players to remain on their current team when a new round starts. If zombies win, everyone will remain on the terrorists team.
Fixed invalid handle error after a map change.
Fixed language code typo in translations.
Infection countdown is no longer displayed if the infection delay is just one second.
