Added the drop chance in the config file.

Added a command:
/combatrevamp <book/scroll> <skillname>

example:
/combatrevamp book arise : this will give you a book with the ARISE skill
/combatrevamp book lightning_strike: Will give you the book of Lightning Strike.

For the Scroll, you just use the first word of the scroll name
/combatrevamp scroll steal: will give you the steal scroll.
/combatrevamp scroll magnetic: will give you the Magnetic Force Scroll.

I only tested this for a few hours, not sure if it has any error or something, so far none on my end, if you found any, please post in my discord so I can address it, Thank you

Bug Fix:
There's an error where if you try to rename any item in the anvil, you will get error, this is because of my poor man's achievement implementation, I already fix this, if you still encounter this please post it on discord

Current Known BUG:
I just realize this now, since the level of items are only base on the mobs name, you can easily hack this by adding a nametag with a higher level to a mob that is a low level, therefore it is easy to kill but will still give you the proper item. Will try to fix this ASAP!!

Changing this to version 1.0.0
