All: Adapt to latest structural changes in 1.12

[jzaefferer]

This is already fixing a bunch of issues with 1.12, but I'm not done. The UI seems to be okay (needs more testing though), but downloads fail while trying to strip banners from built CSS files. Haven't yet figured out what's wrong there.

This is an incomplete fix to deal with the new folder structure. Widget-to-widget dependencies are still broken.

Seems good. Please, just let me know if you need clarification of the existing code.

Yes, I could use some help. This fails because data is undefined: https://github.com/jquery/download.jqueryui.com/blob/master/lib/package-1-12.js#L190

I still have no idea why. path is "dist/themes/base/core.css", I don't know where the "dist" part comes from.

This is a questionable amount of processing, but seems solid enough.

As you may have noticed everything is so better modularized now. So, I think a good first step is making sure that https://github.com/rxaviers/builder-jquery-css still works after UI file changes.
