[Orgmode] Automatic indentation of org tree

[User]

I put this package here too if someone's interested in developing
it, because it's unlikely I will have the time to work on it.

Once loaded M-x orgindent-activate activates indentation in the
current buffer, so everything under a header is indented
according to level. Default indent size is 2
(configurable).

There are some unpolished parts in it (e.g. the header regexp is
hardcoded), but aside from those, it seemed to work well in the
few tests I run.
