Small new hack for FE7 and FE8 - this allows you to give a Hit bonus to Enemy (And/or NPC) units. By default the bonus is +10 hit to enemies, but this is fairly simple to change. You can also optionally have this bonus only apply on Hard Mode.
The current version hooks into the main Hit calculation routine; I plan to move it to a better location and perhaps integrate it into my weapon rank bonus hack, so you might want to hold off on applying this for now.
