implement ingame time format setting

Convert ingame time to millihours and calculate the timestamp from this.
It results in a default timestampo that is parsed by default date and
time functions.

Replacement variables:

{24h} = 24 hours time
{12h} = 12 hours time
{min} = minutes
{its} = ingame timestamp

For some reason I was not able to get the am/pm indicator (`%p`) so 12
hours format is only the time and no optional indicator.
