Now merged in /noblogs/ai-buddypress-plugin.

child themes are not in this repo anymore, they should all go into
noblogs/themes-child

These patches only touch configuration files, and we have those
shipped as part of the container in ai3/docker/noblogs!6.

Fixes issue #2.

- 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)

removing patches from commits with added/removed plugins, or modified files which we have now moved outside of this repo (e.g. r2db)

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.

added a theme and a patch as an example

The patch is taken from the git repo noblogs-wp.
It does not apply cleany (yet), since there is an annoying issue with mu-plugins.
They have to be single files, but they are not distributed as single files.
There is a tool which auto-loads them, but I think the mismatch in the directories still causes the patch do not apply nicely.

We have few mu-plugins and we do not update them often, we could think of some solution specific to this problem later.
