Changing FE7's weapon effectiveness factor

Eh, once you know what this routine does, it’s just a matter of looking it up in a table and multiplying by that. Though it’d be interesting to see if he did it in-place or had to repoint it. I wrote this one in place so it’s not intrusive to change it.

He did repoint it, which is fair, since it does allow for more flexibility than before.
