How does it work?

How the mod works
When a user with the mod joins, it sends the mod list of the client to the server. The server then saves the mod list to a folder called "PlayerMods".
The saved mod list comes in this formatting

Player : [Client's Minecraft Username]
Mods :
[MOD NAME] : [MOD ID] (Server does/does not have this mod)
etc...
