Request for Colorful Larry Skin Support

[texxasrulez]

If you would like to add support for my skins, here you go. I have done some CSS changes to mimic stock login with persistent login checkbox for Larry based skins. I also changed verbiage since stating DO NOT USE may cause some users to feel unsafe using this plugin if they do not know all they have to do is make sure they log off when done using a public or someone else's computer. I do thank you for considering a merge.
