This moves the various projects from "type-based" folders (such as
"services" or "tools") into more appropriate semantic folders (such as
"nix", "ops" or "web").
Deprecated projects (nixcon-demo & gotest) which only existed for
testing/demonstration purposes have been removed.
(Note: *all* builds are broken with this commit)
Removes acid-state specific code and the former BlogDB module, in its
stead the new BlogStorage module contains stubs for the functions that
will be filled in with DNS-based storage.
This code is unformatted and will not currently serve a working blog.
