Key binds get reset whenever pack updates

[chimericdream]

Because the key binds are stored in the mod config rather than with the rest of the user-level options, any time I update my modpack, all of the players on my server have to reconfigure their local instance to map their preferred keys. I'm curious if there was a reason for implementing your own method of storing key binds rather than using the same one as most other mods (and vanilla MC itself). Would it be possible to change that so we don't run into this in the future?
