Replaced jquery-ui.min.js with un-minified versions.

Hi,

I'm the Debian Developer who maintains the kivy Debian package. To make kivy compliant with our requirement to proved the source for *all* files, I had to replace the minified .js files with the original ones from jquery. In that case only effects.core and .slide where affected (I think). I just concatenated both files onto a new one and renamed the reference in `layout.html` to the new filename. This fixes [Debian Bug 736734](https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=736734).

Could you please double-check if it works and apply it to your source tree? I know this probably sounds very strange, because technically the minified js-files are still source files, but I didn't make the rules and Kivy has been removed from Debian/Testing because of the minified versions.


Thanks and Cheers,

Bastian
