skillmod v0.2 - Fighting fix

Extract the archive into the folder "mods" in your server directory.

If you don't have any such mods, please install ago's modloader first.

Now properly scales Fighting skill as well.
Beware though that i didn't fix some "bugs" in original code.

You CAN get more than 1FS per tick.
If you would get more than 100FS, the gain is divided by 100.

This means in practice that you need to be careful not to have too high skillmodifiers for fighting skill.
