It seems we don't need all the development files. Though it feels a bit
evil not to keep them. Then again we didn't have the whole dev-tree there.
Really we should maybe use git submodules for this?
I also made sure that if we don't have minify enabled, a non-minified
version of jquery-ui is loaded, as minification is the most evil of all.
Bad as hell to debug, and anyone visiting the site should be allowed to
view all scripts that are run in an overseeable manner.
