hardreset: Reset ingame_titlemode

You'll note that getting in to the glitchy state of the game (the state
where you could play the game after it had hardreset() called on it)
required the player to quit to menu with ingame_titlemode set to true.
Well, quitting to menu calls hardreset(). So if hardreset() is called
when quitting, then you can no longer preserve ingame_titlemode that
way. This is a bit overkill, but I'm just taking precautions.
