@title Configuration file merger/differ.
@about This script allows you to diff two config files and select which value to pick between the two.
It will then give you an updated configuration file with the settings you chose.
How-to: a) Paste both versions of your config file, submit the form.
b) Select values you want to keep in the next form, then submit said form.
c) Copy the output'd config file and profit!
Note: if either one of your config file has custom values, make sure that it is set to be the NEW
config file on the first step (right hand textarea). This will be adressed at a later date.
