Licensing

I decided to use the GNU GPL. It seemed the most broad.

I'm not sure if I did this correctly, but my Google SVN project repository contains other people's scripts (like Prototype, YUI Color Picker, jQuery, etc.) that have their own licenses, etc. All the scripts I used are open source libraries, but I'm not sure if including them in my own repository is ok. Should I have just told the user to download them themselves or is it ok to package everything together like I've done? In any case, I think it's ok to put everything in one place.
