added and adjusted the following features by zwwooooo to help restoring IoV to a pure item mod:

- externalized the brightness vision range modifiers to allow for different ratios of day/night vision range
- added <PercentRangeBonus> as a complement to <Rangebonus>
- added the possibility for LBE vests to function as plate carriers

These were the missing features from IoV previously not in the 1.13 trunk. Thereby, IoV is now fully compatible to the current trunk (by DepressivesBrot)
