Renamed FIX_KEY_CROUCH to FIX_DriveBy + Improvment

I have improved FIX_DriveBy to work better than before.
However i want to know why
random, HideMenuForPlayer_2 and file_inc are default disabled
1)if we set random to 1 i think is not a problem because no one pass negative number to random because it generate a non-sense number. So if we enable it is only positive.
2)HideMenuForPlayer_2 i think that this have to be 1 too because the real function expected the menuid parameter so i think that have to be setted as Fixed by default
3)Why file_inc are disabled? is someone don't use file function it can simply disable it. I think that are more the people that use it.
