How can I set the default game duration?

[Vikti]

Is it possible to change the default game length for "Normal" mode? By default it's 3 minutes, and I could not find any related option in `gameinfos.inc.php`.

// Time in second add to a player when "giveExtraTime" is called (speed profile = fast)
'fast_additional_time' => 30,

// Time in second add to a player when "giveExtraTime" is called (speed profile = medium)
'medium_additional_time' => 40,

// Time in second add to a player when "giveExtraTime" is called (speed profile = slow)
'slow_additional_time' => 50,

These are the additional(!) times, I'd like to set the default, starting time.

I assume it's a multiple of those values.
