Make input events use earliest possible time

Browse source 
SDL doesn't provide exact the exact time that input events happen
so use the earliest possible time that an event could happen.

This make sub-frame input actions such as walking take affect
immediately instead of in the next frame.

Based on patch by Alexander "wareya" Nadeau.
