Derivatives of GM_config must be licensed under the LGPL

[sizzlemctwizzle]

After looking at the code and your site, it is very clear this is a derivative work based on GM_config which is released under the LGPL. Therefore you can't license this work under the MIT license. I don't know if you modified GM_config source (in whole or in part), but I can tell that you at least used the source as a reference to write this. I highly doubt you black box reverse engineered GM_config.
