- moved themes related patches to patches/themes (yet to check)
- moved wp core patches to patches/core
- split the mega-patch for hyperdb in the individual edits. I removed the one related to nextgen-gallery since I think it is not relevant anymore (but I might be wrong)

I have excluded the commits that added/removed entire
plugins/themes/languages, since we really want to only keep *actural*
patches to upstream code here.
